DNA components found in meteorites

NASA researchers have found the building blocks of DNA, the genetic molecule that is essential to all life forms, in meteorites, pieces of space rock that have fallen to Earth. The discovery suggests that similar meteorites and comets may have impacted Earth and assisted in life formation here.

With minimal chance for contamination of the meteorite samples, scientists are confident that these meteorite specimens were formed in space. “People have been discovering components of DNA in meteorites since the 1960's, but researchers were unsure whether they were really created in space or if instead they came from contamination by terrestrial life,” Michael Callahan, lead author of the study on the discovery, said in a statement.

The research team analyzed twelve carbon rich meteorites, nine of which were from Antarctica, to positively identify the basic elements of the chemical compounds they extracted from the samples. Testing revealed adenine and guanine, two fundamental components of DNA called nucleobases.

DNA is shaped like a double helix, or twisted ladder, and the rungs of that ladder are each comprised of two nucleobases, either a pairing of adenine and thymine or of guanine and cytosine. The ladder is essentially a long string of genetic code that tells cells in an organism which proteins to make. Those proteins then play critical roles in organism growth and function, making everything from hair to enzymes.

Scientists also found hypoxanthine and xanthine, two other chemicals used in biological processes and found in muscle tissue.

The meteorites also contained trace amounts of three molecules associated with nucleobases, called nucleobase analogs, but two of those are almost never seen in biology, providing the necessary proof that these DNA components were actually created in outer space.

In fact the only record of any of these nucleobases in biologic processes is within a virus.  Callahan said in the NASA press release that “if asteroids are behaving like chemical 'factories' cranking out prebiotic material, you would expect them to produce many variants of nucleobases, not just the biological ones, due to the wide variety of ingredients and conditions in each asteroid,” and that is exactly what these researchers found. He says the nucleobases found, biological or not, can also be created in a lab setting, using the basic compounds hydrogen cyanide, ammonia, and water.

This finding contributes further to the growing collection of evidence that asteroids and comets are comprised of the proper chemicals to generate the building blocks of life. Some seem to have the ideal internal chemistry for the job.

“In fact, there seems to be a ‘goldilocks’ class of meteorites,” Callahan said in a statement, “the so called CM2 meteorites, where conditions are just right to make more of these molecules.”

    Adenine decomposes at 360 degrees celsius...when meteorites fall to the ground, they get much hotter than this...any amino acids on this rock should have already decomposed/evaporated from the meteorites shortly after they enter the atmosphere

    ...am I missing something?

    CNN can't even draw those chemical structures correctly. Look at the valence of the atoms on those purine rings (nucleobases). For example: The carbon-oxygen bond on the rings should be double (carbonyl) not single, making the adjacent carbon-nitrogen bonds single rather than double. What a bunch of retards. And like others have pointed out, this is not DNA, just bases. They're missing sugars, phosphates, and, most importantly they'd need to be in the form of polymers linked via phosphodiester bonds.

    What rubbish. This propaganda is titled DNA discovered in meteorites, but goes on to say that a chemical that is also found in DNA has been linked to meteorites, and that scientists are "confident" of that. This crap makes meashamed to call myself a scientist. That's like saying I think I found ink on a rock from space so I'll conclude that The grapes of wrath originated in space, or that Boeing 747 came from meteorites because I think I found a metal common to both. This pseudoscience trash should be derided. DNA is far more complex than just a base, is highly structured, and encodes INFORMATION.

    Do a bit of reading about Quantum Physics, interesting stuff that seems to hint some zen philosophy is not as far-fetched as "modern" society thinks. I find both fundamentalist religious zealots and atheists to be two sides of an amusing, inflexible, dogmatic coin. To believe in medieval fairy tales, or to be so arrogant to assert there is poitively no chance there are cosmic wonders we do not yet comprehend, is almost equally void of reason.

    In the Qur'an, Allah reveals that the creation of the human is a miracle. The first human being was created by Allah shaping clay into human form and breathing a soul into it:
    Your Lord said to the angels, "I am going to create a human being out of clay. When I have formed him and breathed My Spirit into him, fall down in prostration to him!" (Qur'an, 38:71-72)
    Then inquire of them: Is it they who are stronger in structure or other things We have created? We created them from sticky clay. (Qur'an, 37:11)
    When the human body is examined today, it may be discovered that many elements present on the earth are also to be found in the body. Living tissues contain 95% carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur, with a total of 26 different elements. In another verse of the Qur'an we are told:
    We created man from an extract of clay. (Qur'an, 23:12)
    The Arabic word "sulala," translated as "extract" in the verse, means "representative example, essence." As we have seen, the information revealed in the Qur'an 1,400 years ago confirms what modern science tells us-the fact that the same elements are employed in human creation as those found in the soil

      A bit of a stretch. Don't understand why followers of the three major monotheistic religions go to such efforts to try to take ancient stories / fables aka their holy scriptures and reconcile with modern science. I can accept that there is some element of organized religion that attempts to understand the sacred, to be good stewards of this planet, and hints towards a unifying theory of the universe ... but beyond that ... dogma, rhetoric and intolerance is what I see.

    Basically, AA, who cares. O.K., you found a few nucleotides on some goddam meteorite. That's like going to the moon and finding aluminum and deciding that proves the moon used to be the earth, or someting. Right? Pelagebacter ubique, which is the only reason there is any oxygen in the Earth's atmosphere at all, has existed in the ocean for what, three billion years? No attempt to completely explain its DNA has yet been published. Instead the USGOV wants to throw more billions out the window on a few idiotic molecules on some stupid asteroid. I mean you don't even know what's on this goddam planet! Either you're here or you don't exist. Nobody from this country is going to discover anything in outer space, and if they did, they'd probably contaminate it and destroy it. O.K., here are the three principles of American scientific research – AA, AA, and AA. You is done gone be broke, man. P.S. the Moon is the "Twin" of Mercury.

    Funny how some people will say, "yeah, maybe it lead to the development of..." apes, but not humans.
    Or, maybe science can explain some things, but the things that aren't explained must be GOD, as if science isn't ever-learning.
    Why not just, if you absolutely have to have a Goddish-type reason to accept science, look to the Vatican scientists? The Vatican has a great science department and understands that you can mesh science and theology easily.
    Some of you might have to look up the word "theology", as your grandaddy and local preacher probably doesn't use that term in conversation or in brimstone chats.

      I'll leave you with one thing to think about, and them I'm out. I'm the type of person that believes in God (or a higher power if you prefer not to name names), because of things I look at in the world and think about with my own eyes. There are some cool things in the Bible, don't get me wrong. Like Leviathan, Behemoth, Ezekiel's wheel, etc, and there are inspirational stores in it as well, but from my science mind, I like at the physics of this world, and I think about numbers, and odds, and math, and chemistry, and I look at nature, and the complexity of our bodies and how they manage to function the way they do, and I can't help but see intelligent design. The odds of all of this happening by chance just seem so astronomical, that I can't bite into the "accident" theory. And here's the one thing that always seems to trump every theoretical idea about evolving gradually into what we are: I met a man once, who was schooled in theology, an ordained minister, a tree hugger, kayaker, granola eating, earth loving, liberal, and believer in God. Crazy huh? It's true though. He looked like Friar Tuck from Robin Hood. He was pretty amazing, and I could listen to his theological and scientific reasoning for hours sitting around a camp fire and drinking beer. Towards the end of his story about how he came to his conclusions after struggling for a long time with his beliefs, he said this, "I always found it hard to swallow evolving slowly into the amazingly complex machines that we are today. And one day I had a thought that made me realize that it had to be non-sense, at least for me. I asked myself how could we possibly evolved from non-seeing little creatures that crawled out of the ocean, to having such complex eyes that can not only see, but see in color and 3D? Because, you cannot simply just go poof and evolve into having eyes overnight. Yet, you also cannot slowly form parts of eyes if your little body doesn't have a place for eyes nor know the need for eyes. How would eyes create themselves on a body without eyes? Did they develop optic nerves first, but nothing else? What would be the purpose? Did they then develop the globe of the eye, but not the rods, cones, corneas or retinas? How the hell would a body know it needed eyes? When did the skull create sockets for the eyes? It makes no sense that eyes would either come to be overnight, nor would they form in bits and pieces. They must have been created."

      My jaw was on the floor when he said this to me. Who thinks about things like that? But he is right, and if you know anything about evolving and the body, you know it's a very very "eye opening" point.

      Think about it.

    No real DNA was actually found. Just the building blocks of DNA, which apparently are expect to for under such environmental conditions.. The tittle of this article is all wrong. And the theory of this DNA planting the seed of life (in response to some person who posted a question about it) probibly refers to the meteorite containing some form of viable life form such as a small bacteria, which perhaps in a sporical form could survive a travel through space. Although unlikely, even 1 viable bacterium could thrive n proliferate in the proper environment. After the bacteria replicates mutations are made randomly and through a process we'll call "survival of the fitess" higher level species can further adapt to their surroundings through adaptations.. And BOOM here we are. Thoughts n emotions probibly stemmed from traits originally created to help us survive, the ability to think on a higher level allowed us to hunt, have tools, clothes we use to personally adapt to environments we werent suited for, and then one day some extra smart dude made up morals and taxes.. And then an even smarter dude made tax brackets for the poor n wealthy. And theirs the theory of life on earth being seed by a rock in space. Read Charles darwin and
    Mendel (he had a bunch pea plants n he lived in a monastery.. It's a real deliteful story that ultimately helps support darwins beliefs). If u look up LaMark (if that's how you spell his name, maybe lemark) ull discovery how support ppl are and if u read about something called spontaneous generation.. It's all true (small joke). Peace.

    One million years ago a rock was launched into space by some person or thing from another Earth far more advanced from ours. Today, it just happened to make its way into our Earth safely. Then this unique rock, which we call a meteorite, was discovered by a scientist who believed it could answer all of his unanswered questions.

      It proves nothing. That's the point. Trying too hard to find proof of a cosmic chemical accident that created morons that can walk on two legs and talk, is just as bad as trying to prove that it's all divine creation. Neither can be proven. It's about looking at all sides and then deciding for yourself. You are a good case for what I was talking about. The smart ass "reaction" from you pretending to have the "most" intelligent answer with that arrogant attitude is just a front anyway. You don't know the answers anymore than me or anyone else. You just want people to believe you do. Acting macho is really not as becoming as you think it is. By the way, are you a sport, a Java applet or an Ewok?

        See, I like that, too. THAT'S meshing science and theology together. Maybe the Bible is an eloquent and antiquated writing of scientific events. Maybe it's sometimes more literal than what many Christians think it is. Why do a lot of people ignore the very amazing and yet significant things in the Bible like Leviathan and Behemoth, or Ezekiel's wheel, or the burning bush, or that perhaps give credence to Biblical events such as there being over 500 flood stories from different cultures in history? How many people ever think that maybe stuff happens, and people document it, even if it is in the form of the Bible which happens to combine both the views of spiritualism or faith, and that of historical events and/or scientific events? Why can't the Bible be a container for some scientific answers, just like any current text book written by the hand of imperfect humans? It can go on and on.... it just takes a little bit of brain power, honest feelings and an open mind.

    @ Alosha, Questions for Atheists and Sharp: Bravo to you for adding some truly intelligent thought to this thread. I'll be even more impressed if one or more of you isn't even sure you believe in a "higher power" and yet, still have the wisdom to not necessarily argue against it because you use logical reasoning. Way too many people either just believe something or don't believe in anything, and can't really give you a "rational" reason why. Nothing is more impressive than those who can generally view things from both sides of the fence and weigh the answers to form their "very own" conclusion vs what they have been taught or told by someone else. You guys are the only type that keep me remotely interested in reading posts on any CNN article.

    @ Kazz... is it REALLY that exciting, this news? From this article, we don't even know if they cracked the rock open and found this "evidence" in the middle, or if it was embedded in the outer crust. And even then, as Alosha stated, it really means diddly squat (not his/her exact words). Scientists like these always get excited over little finds and then hype the hellsinky out of them, because why waste a 6-figure education and their scholastic belief system. Plus.. scientists and engineers are never wrong (Sarcasm). Trust me, I know a few of them. And I almost was one (until I said, "Screw Calculus!").

    • David_Forr341

      Yes, but where do those of us who find these scientific explanations as nonsensical and ridiculous as those offered by religion fit in? Granted, religion is a man-made construct that allowed the unknowing to explain the unexplainable... but our science is rudementary and riddled with error when it comes to formulating any type of advanced analysis. I don't hang out with the atheist community because they spend all their bandwidth fighting the religious community instead of trying to prove their purported religion: that there is no God. However, I believe you can subscribe to the idea of a divine Creator who cannot be explained with this blunt instrument called science. I can't prove it, of course...but I can feel it. Science can't prove that I feel it but I know that I do. I don't feel compelled to explain why I feel something that atheists can't. Just lucky I guess. If science ever does provide a solid counter-argument for "accidental" creation, I'm all ears. But last I heard, science can't even create the most simple form of life in a lab. What's up with that?

      August 12, 2011 at 2:14 am |
      • ?????

        To call atheism a religion is to call not playing the violin a talent. The reason why atheists do not put forth evidence to support the stance that there is no god is because it is not necessary. Why is this?

        Why is it necessary to prove something to not exist? The burden of proof is upon those who insist something exists. To attempt to proof that something did not exist, one would have to examine every speck of the universe. To prove that something exists, one just needs to provide one solid piece of evidence.

        As for your claim that scientists cannot create life in a laboratory, http://www.thesun.co.uk/sol/homepage/news/2981138/Scientist-creates-first-man-made-cell.html

      • @?????

        "Why is it necessary to prove something to not exist?"
        here is why: Remember the "ether" theory?...the experiment that proved the "ether" does not exist made possible the discovery that the spped of light is a constant independent of an observer state of motion.
        But your problem is that you cannot prove that what you do not believe to exist does not exist, because its unprovable!...and thats what drives atheists crazy!

      • ?????

        The point of my question was to reveal that things are allowed to be assumed to not exist. Without direct (or indirect) observation, it is wrong to say something exists. Because religion insists that there is a god, it is logical that they provide proof. The aether theory assumed that if aether existed, _____,______, and ________ would be observed. Because these things were not observed, it is logical to conclude that the theory is incorrect. The intent of the experiment was to test the hypothesis and to reach a conclusion. That's how logic works. You say, "Okay, if _______exists, then_______ will happen." And if that second _______ does not happen, then your hypothesis is incorrect.

        My overall point was that the burden of proof is upon religion, not upon atheists.

    To everyone in the field of research, continue searching for the answers to the mysteries of the universe and our very own existence, keep up the good work. Those who cannot accept "intelligent design", my preference being GOD, normally have no theory at all because they can't believe that which they can't see. Faith is easily defined, but how can we describe it to one without it? As you walk, there is never a single thought given as to whether your legs or feet will support you. You have an unconditional belief that they will. On creation here's food for thought! GOD and man in the dessert. Man tells GOD, we have evolved and I can create anything that you can. GOD reaches down, picks up a hand full of dirt, creates a man. Man reaches down, and GOD says, hold on, make your own dirt! Great discussion folks. GOD BLESS!!!

It was a fantastic program that paid the U.S. back many times over. Only our short-sightedness has caused us to scale back the exploration of space to its sadly-reduced status. I guess we will leave it to the Chinese to explore and acquire the vast resources within our own solar system. It is as if Columbus approached the Spanish crown and asked for funding for a second trip to the New World after discovering the Americas, and they said, "Nah, you've already checked it out, and we've got a bunch of social programs that need funding...so we have decided to scrap the whole global exploration program."

    Just because they were able to find a few of the ingredients present in dna doesn't mean that first of all that dna could be randomly created. Secondly, even if it could be randomly created, the odds that it would make enough sense to create a viable mono-cellular organism is tremendous, owing to the complexity of dna. Thirldy, all cells fit into two main categories prokaroyotic and eucaryotic and they require most of the same parts to function i.e. the odds that even one cell could be randomly created is astronomical. Fourthly, a single cell would still be no where near intelligent life. Conclusion= a few building blocks doesn't equal a skyscraper.

      You're right it doesn't. But at the same time it is a start to see other possibilties of how life started on Earth other than "God did it".

      The religious are always saying "then where did x, y, and z come from". Well we found a potential source for x, and this may also one day lead to y and z. The difference between religion and science is science is willing to admit that it is not all knowing, and attempts to learn while religion attempts to claim it is all knowing and discredit anything that contradicts it.

      Your comment indicates a lack of understanding of natural biological processes. There isn't anything "random" about it. Nature is infinitely patient (and I don't mean in the anthropological sense; I mean in the mathematical sense). So over thousands or millions of years, chance changes occur (this is probably where you get the word "random"). If these changes function in such a way that the organic compound functions better, it is replicated. Eventually – again over millions of years – the collection of organic material has become more complex; we might now consider it an "organism." What makes this process "not random" is that all of the iterations that didn't work well die. The ones that have an advantage pass along their structure, their code, their DNA. The point is, it takes millions of iterations to develop tiny improvements, but the test is survival and it is ultimately a dispassionate "pass or fail" barrier. It isn't random. There is a reason you have fingernails and toenails, although they may not be as essential as they once were. There is – or once was – a reason you have the vestigial organ we call the appendix. There is a reason you have an atrial appendage that no one understood for a very long time, but it turns out to have functions we did not appreciate until recently. None of it was random. The conditions that forced – the word "forced" is deliberate – certain developments may no longer be present, but if those changes (the appendix, etc) aren't actively detrimental to us in our current environment, it may take a very long time until they disappear. But there is nothing "random" about it. Something truly random would be like God choosing to save the populations of the Eastern Mediterranean, but not North and South America, East Asia, the continents of Africa and Australia and the islands of Polynesia, or the rest of Europe. Random would be like the stories humans make up to explain the world around them, which they don't understand, and then ascribing their stories to a supernatural entity who is never seen or heard, but who speaks (silently) to select, self-appointed spokesmen. Why the Creator of the entire universe would behave so randomly has never been addressed.

        And still the laws of physics are an "embodiement" of mathematics. In this sense someone could say that mathematics "causes" and "controls" the material world through the laws of physics. It is amazing to see how nature "obeys" mathematics, especially in quantum mechanics.

      True dat. It's really retarded to call these chemical processes part of the beginning of life. They are fairly simple chemicals, they are paired with hundreds of other simple chemicals that have significant chemical stability to not react. The fact dna or proteins can be "made" from these chemicals is a scientifically inconsequential fact that does not lend credibility to any abiogenesis claim.

    I'm guessing that meteors did probably seed primordial earth causing life. So then there is a current way for life to spread throughout the universe. But how effective is this way? It took chance and billions of years to develop higher life forms capable of enduring. Is there a better way? Life, if it as a whole is adept at survival, capable or has any purpose, must continue at all costs.... it must evolve to create a way off its home planet. Planets never last but life must endure. If evolution incorporates long-term survival then 'smartest' thing that could evolve would be organisms that had desire to develop the technological capability to venture and seed other planets. Aka...man and his excitement and wonder of space to build a spaceship or other way of colonizing other plants. Seems like a better way to me than random meteors.....and maybe a natural way that all life on any planet ultimately evolves into.

    @INVISIBLE EVIDENCED I agree with you completely. I constantly find that science and spiritual beliefs go synergystically, hand-in-hand, one solving the mysteries of the other. As regards creationism, I think, it is simplistic to believe we evolved from apes; so what that we share 98% DNA. We also share 97% DNA with a banana. And if we are evolved from apes- why are there STILL Great Apes, a species unto themselves? But this glorious NASA discovery ties in perfectly with Genesis, where the Bible opens upon a dark, void, and formless world. The divine light of the Cosmos was struck, the light came on, mattet exploded, and the myriad complex – and basic, simple, – processes of life...cell division, protons clinging to nrutrons to electrons – the building blocks of lifr swarmed the expanding universe impregnating planets whose characteristics completed the formula for life in the myriad forms we knoe. How amazing it is that the supercollider at CERN shows no matter how "small" we dig into particle physics – the matter is STILL THERE, ever tinier, but awesomely important. And it's mind-blowing that the scopes at the Jet Propulsion Lab in Pasadena and the Hubble telesxope show us no matter how BIG AND FAR we dream and search, the universe and it's quantum mechanics and physics secrets ARE STILL THERE TO BE DISCOVERED. We truly ARE made of stardust! "Ashes to ashes, and dust to dust..."

    • WeareallIgnorant

      To answer your question on the great apes theory: Humans did not evolve directly from apes–but a common ancestor–that existed about 5 to 8 million years ago. Diverging in Africa, this species created two separate lineages that happened to be chimps and hominids–aka early humans. That is why modern great apes still exist today. It's a common misconception that many people seem to have with the evolution of our species–homo sapiens–and honestly it probably has to do with religious people skewing facts in order to try and prove their point better.

    It seems that every time a story comes out about the wonders of the universe it always breaks down into a religious debate that is frankly quite irritating. The recent discoveries and observations in science are flat out ignored by the religious right, and some of the valid questions by the religious right are ignored out of spite by the scientific left. Two common questions are asked by the right that are often ignored by the left. I'll strive to answer these questions using as close to layman terms as I can.

    1) If there was nothing to begin with, where did everything come from? (Creationist trying to disprove science through coercive questioning)

    One of the basic precepts of the universe is that energy cannot be created or destroyed. It can be converted and it can be stored. Before time, there was energy stored in that whence came the Big Bang. Matter is energy. Just condensed into a solid state. The equation e=mc2 (E equals M C squared) is the most well known representation of the relationship between mass (matter) and energy. The Big Bang Hypothesis states that before the universe there was nothing but a massive, for lack of a better way to put it, black hole. We're talking extra-super-duper supermassive. There is no way that the common human can even comprehend how massive it was, you'd have to be a quantum physicist to even come close to understanding the sizes we're talking about here. The theory goes something along the lines that the original black hole basically exploded, and what was released was not quite matter as we know it, but instead sub-atomic particles that, due to the explosion, were crammed together and started forming the most base atom known... Hydrogen. As the hydrogen started to draw together it formed massive stars. Millions of times larger than our sun, these stars were very short lived before they blew apart, but in the process fusion occurred and heavier elements were formed; Helium, carbon, iron, etc. From these exploding suns were also formed the first progenitors of the galaxies, the first black holes. Matter was trapped in the gravitational fields of these black holes, forming proto-galaxies (due to distances, the farther out we view, the farther back in time we see, and we can still find some of these proto-galaxies today!). Repeat the process of forming stars for a few billion years and now the heavier elements get heavier. They start forming the initial planetoids. Massive planets, like the ones found in orbit around other stars create a different form of fusion in their core, and the extra heavier elements form. Through the process of destruction and recreation eventually you get to where we are today, with a diversity of elements that interact in ways we can barely begin to understand. Thus life.

    2) If there was nothing before the Big Bang, where did the void that the universe is expanding into come from?

    There wasn't a "void" for everything to spread out into. Before the Big Bang there was quite literally nothing as we understand it. We are creatures fixated on time, and before the Big Bang time itself did not exist. As for what the universe is "expanding into," it is sub-space. A non-time or space related area that, quite frankly, is so far beyond my comprehension that I can't even begin to try to describe it. Suffice it to say though, if the universe continually expands, it will still never reach the edge of sub-space because there is no edge.

    Any of this could be easily researched if people were to but take a few moments of time to do the proper research. I'd suggest starting with the research done by Galileo, so you can gain an understanding of how our solar system works, followed by some of the findings of more recent scientists (Hubble, James Webb, etc), and then finally move up to more diverse and incomprehesably brilliant scientists like Einstein and Hawkings.

      Perhaps this will help. The Lord, Allah, Jehovah, Lord Krishna or whatever God you might believe in Abides by the rules & structure of the universe he or she or it created. All religions that try to dictate the minutiae of creation are trying to assert authority as a means of extending their power structures. ALL RELIGIONS ARE BASICALLY POLITICAL ENTITIES. Whatever faith you might profess this is gross disrespect towards your God. A far more interesting question is whether God is part of creation ( that is God IS the creation) or stands apart as a puppet master. I find the former more satisfying but there can never be a proof .

      August 12, 2011 at 12:44 am |
      • MOCaseA

        The statement that all religions are in essence political entities isn't far from the truth. However regardless of how accurate and specific science can get on the origination of the universe, there will always be the possibility, or idea of the possibility, of intelligent causality. There is no way around it, and I accept that fact. But to make a statement of fact that the only possibility is intelligent causality, that irritates me to no end. So I was just throwing out there what is currently known, based on some of the most recent documented discoveries, as hopefully a way to draw this into an intelligent discussion, rather than a sling-fest of "My way is better than yours."

        August 12, 2011 at 12:56 am |
      • Sharp

        The final decision about the universe being created vs self created as a belief is a personal one. The classic argument is that the universe is made to a wonderful & infinitely complex plan. A plan which mankind has almost no chance of ever fully understanding. Anything made to a plan has to have a planner. So it all boils down to that inductive leap. A plan requires a planner; God. I probably doesn't really matter, least of all to God.

        August 12, 2011 at 1:25 am |
      • MOCaseA

        Again your argument, despite attempting to be equally sided, is only one sided with the statement that the Universe is based upon a grand and unknowable design, it's laws and physics planned out in order for it to exist. I maintain that the laws and physics are not only discernible, but discoverable, and that nowhere is there an indication of some vast plan for the cosmos. The "design" you speak of is strictly a personal belief based upon ones individual faith. Thus the "plan" has no basis in science without some form of scientific process in order to bring about it's validation or debunkment.

        Sticking strictly to the known facts on hand, yet still allowing for the unknown, there is no evidence of a Intelligent causality, however there is also no proof to directly dispute Intelligent causality. Therefore, I will allow that there is the same chance for Intelligent causality as there is for Self causality.

        Self causality of course being the Universe came into being due to some event still unknown to man, but not due to the direct intervention of a higher intelligence.

    They found some simple organic molecules, not DNA. Nucleotide bases are a far cry from a nucleotide polymer containing information. This discovery doesn't demonstrate anything other than that these types of organic molecules are common in our solar system, which should be no surprise considering that we are here. The discovery is being far overblown.

    DNA self replicates like another class of proteins which cause disease called Prions. (Mad Cow Disease) If such a meteorite hit a sterile earth where proteins & other hydrocarbons had formed non- biologically the contamination might spread & contribute to the start up of life. Another interesting Sci Fi conjecture. What other self replicating proteins might have fallen & caused contamination? Could Prions have caused the contamination instead of DNA? Could life evolve with Prions as it's genetic code carrier instead of DNA? Somebody rough out a script & send to your agent (or grant committee).

    August 12, 2011 at 12:03 am |
    • McGuffin

      DNA doesn't self-replicate. It requires the assistance of proteins and riboproteins in modern organisms. It's thought that RNA was the original information carrier in early life, because RNA can fold into enzymes called ribozymes. In that scenario, DNA emerged as a more stable information carrier (it is double-stranded for error control and without the problem of uracil being able to mutate into cytosine), while proteins took over most of the roles of the ribozymes.

      August 12, 2011 at 12:14 am |
    • Sharp

      I stand corrected. What about Prions carrying genetic code? What about other self replicating organic compounds? This would be the true possible life other than life as we know it. Have silicon instead of carbon based life forms been eliminated as possibles?

      August 12, 2011 at 12:19 am |
      • McGuffin

        Oh for sure it's an interesting idea. Prions are very strange because they really do self-replicate - the prion is a malformed protein that can bind to a normal protein and cause it to become malformed. Kind of cool and scary, but by the way there's no genetic material in prions; they are just protein.

        I don't know much about the possibility of silicon-based life. It might be possible because silicon is in the same group as carbon (likes to form 4 bonds), but I think the problem is that silicon is too fat to allow the sharp turns and such in organic molecules that carbon is capable of. I guess it's conceivable life could have made it work somewhere though? There are organism on earth that respire using sulfur instead of oxygen, which I suppose is the same idea.

    Where did you come up with crap. They're called nucleotides not nucleobases. In an of themselves they do not constitute DNA. So congratulations, the press manages to mangle the facts in the case.

    August 11, 2011 at 11:53 pm |
    • McGuffin

      I agree with you about it not constituting DNA, however you should probably Google "nucleobase" before saying something dead wrong on a forum. Nucleobase is another word for nucleotide base, in other words the actual base part of the nucleotide. The full nucleotide includes the deoxyribose and phosphate group. Nucleotides and nucleobases are two different things.

        How arrogant is the person who believes that the vastness of the universe was created for their sole existence.

        I suppose that the same creator gave you dominance over all the Earth, its animals and its minerals. If so I dare you to go exert your dominance (without a gun, as the original humans didn't have those yet) over a pride of lions or a black rhinoceros. Then once you have exerted your dominance over the said animal and tamed it through His divine grace go to Kilauea Volcano and exert your dominance forcing the eruptions to stop and the vast riches stored within to emerge for your enrichment.

        If you can do this, then I'll acknowledge your preeminence in the universe.

        No, I understood that you meant all of us, and not just yourself. My statement was made of a generality as well, focused on you, the person making the statement of human dominance in the Universe, for making an arrogant and assumptive statement.

        "They are angry because they reject their Father & His love. Many if not most scientists are devoutly religious because they can see the creator's marvelous work in it's tiniest details & because they stand in awe of the master of all artists & his masterpiece, us & the universe he made for us to live in."

        I reject your God, but am not angry. I attempt to have calm and intelligent discourse with anyone any everyone, but there are a few things that set me off. One is the assumption and arrogance that humans are "God's premier creation in the universe, and everything was created for us." The other is "Without God, nothing would be possible." I accept that in Science there is always the possibility of Intelligent Design, or Intelligent causality, but I personally find it offensive when people come to the table with the stance of the ONLY possibility being Intelligent design or Intelligent causality.

    The reason that we are all arguing about this topic is simply because we do not know. WE can believe in science or creation. believing in God is faith which is irrational reason. Believing in science is based upon logical reason and facts however what most people fail to realize is that scientific facts are simply facts because they have not been disproved jump 300 years in our future and half of what we call facts today will have changed and thus attempting to convince each other that one is correct is pointless. What should be pointed out that for all our knowledge both spiritual and scientific we really know nothing of the universe, everything is possible. So just try and keep and open mind

    Sorry to make a bother.

    When it comes where everything came from. Simple answers lies within eternal life believers for those who don't know (Persian Given Name HINDUS).

    Hindus believe in "BRAHMAN". There is two types, but the one we should understand is Nayari Brahman. God, is illusion created by humans, the actual machinery behind the universe according to the old Vedic Texts is impossible to comprehend. Beyond understanding, the universe – according to the text, has always been here in different stages, with no time, with no limit, with no restrictions, calling this a "UNIVERSAL SOUL" and we're part of it.

    There is more to the teachings, and I totally, recommend to research the history. Even though, we Praise the Western World, Signifcant BREAKTHROUGHS in Science and Research was made in the EASTERN CULTURES. Medicine, Cosmology, Iron WORK, Weapons.

    But all praise be with EINSTEIN AND NEWTON!

We are closer now to understanding our own origins as we have ever been. Without any religion.

    Nucleic acids do not necessarily mean that life invariably follows. I find it hard to believe seemingly random chemicals spontaneously form into a complex life form. Think of the second law of thermodynamics and entropy. Even for something as basic as a mitochondrion and its Na/K ATPase; I find trouble visualizing what evolutionary pressures would have causes this to form essentially by "dumb luck."

    I believe in God. Science is just a tool. Contrary to popular belief, you can be religious and a scientist.

      Completely agree, although I am not a scientist. I'm sure we (humans) may have evolved/changed over time (Americans today are larger because we eat more), but to think complex life just somehow spontaneously spewed out of hot water splashing on rocks over millions of years is absurd.

        Of course evolution exists. It is fact, despite the tag of "theory". With that said, this finding alone isn't the smoking gun that proves anything, unfortunately.

        NO! The article is precisely about how these samles are VERY UNLIKELY to have been contaminated. True scientists don't speak in absolutes (like saying "it is impossible that they were contaminated on earth) so that's as clear an opposite to your statement as you could get. Read the article.
        That said, I concur that while this supports evolution (that is, it is in complete agreement with the theory of evolution and evenclarifies some of its uncertain factors such as the beginning of aminoacids) it doesn't prove it.
        But we don't need complete proof of evolution. There's orders of magnitude more evidence supporting evolution than evidence supporting any other theory, so beleiving in any other theory is not justified by rational thought.

        The "Theory of Evolution" has failed so many tests of it's validity that any other theory would have been abandoned decades ago. But, because so many frightened and strident evolutionists have nothing else to hang there hat on except this rotten and crumbling monument to self delusion, it keeps showing up in the pathetically outdated and inaccurate textbooks in our children's schools. The saddest part is when intelligent children try to make a stand and point out the obvious flaws, they are bullied and silenced by "liberal" educators who are only liberal with those who slavishly parrot everything that is spewed out at them. END OF STORY.

        Nothing, by itself, is "proof that evolution exists." The compelling reason to accept the scientific theory as the best explanation for biological diversity (careful avoiding the word "believe," which is fraught with emotional overtones) is simply the overwhelming, vast array of evidence the theory takes into account. I will briefly dismiss the most intellectually challenged fundamentalists who claim the Earth is 6,000 years old. Unless you believe your version of God is capricious and deliberately treacherous, it is hard to account for the alleged creator having hidden literally billions of fossils, from microscopic to dinosaur-sized, in the rocks of our planet. Did He want to trick us? Test us? Challenge us to see through the most intricate hoax imaginable, using His divine powers to mislead and then punish us? If this is indeed your belief, I am finished addressing you, because you have excluded reason from your vocabulary. For the rest of the believers, many of whom are intelligent and well-educated, the burden is to see through your programming, because – like me – you were probably indoctrinated from infancy to accept without question the "wisdom" and "truths" of your religious leaders (and your parents, who were brainwashed before you). THIS HURTS TO CONTEMPLATE. I know that only too well. But look at the world around you – how do you account for the billions of people on the Earth who are equally fervent in their belief of Allah, or Scientology (cough, cough), or the Book of Mormon, or the hundreds or thousands of various religions CURRENTLY practiced, not to mention all those that have gone before?

        Evolution is not "belief." It is a theory of the mechanism for the constant change and specialization that takes place continuously in nature via the sternest measure of all: change that is advantageous allows survival; change that is disadvantageous is rewarded with extinction. From microbes to macrobes (like you and I), we see the evidence everywhere in nature. But scientists don't BELIEVE in evolution; is it an explanation, constantly being refined, revised, and modified to reflect what we are learning about the universe around us. Contrast that to religion, which despite having supposedly direct input from the Supreme Creator, did not even know about microbes, so that people could have been taught to wash their hands after defecating – which alone would have spared millions from unpleasant, early death. Surely Jesus would have known about micro-organisms, would he not? Why would he "not bother" to mention it to his followers? He didn't seem to be aware that the world was not flat, as most people of his time believed. Nor that HALF of the world was unknown to the primitive peoples of the Middle East. The Son of God, sent to redeem mankind, ignored all of North and South America, China and indeed all of Asia, as well as Australia, the islands of the Pacific rim, and for that matter, the whole of Europe – which was an unknown "pagan" region at the time.

        You "believe" as you want. I choose to constantly learn and adapt as new knowledge is acquired. We live in the time when knowledge is increasing more rapidly than ever in human history. Yet as always, organized religion is fearful of new knowledge. Why? Have you asked yourself this? It is because it threatens to encourage people to think and reason for themselves, and not be dependent on their "religious leaders" for direction and control. Make no mistake: religion is first and foremost about control in the here and now. Try telling your church leader you have decided you can't afford to tithe any more and see what they say about that.

        Abiogenesis does not occur simply by "random circumstance". In any system where protein formation is high, self-replicating proteins will naturally end up dominating the system over time. It's much like natural selection, except on a molecular scale.

        The implication you make that "great odds" are required for abiogenesis is entirely correct. This is probably why we don't see intelligent life forms everywhere we look in the infinite cosmos. It's not cause for alarm at our own existence, however.

And that you further defend the photo as nothing more than a picture of space stretches incredulity to the point of suspicion that you are related to the story's author. You and I both know that 99 out of 100 readers will think they're looking at a meteor shower.

      I despise how many commenters are more intelligent than many media writers attempting to reinterpret primary or secondary sources into headlines. Headlines meant to regurgitate science into lay people speak are both are purposely being misrepresented to draw readers and unintentionally due to the authors' negligence, ignorance, etc. I'm not saying science doesn't misconstrue data and extrapolate conclusions, but the majority of scientists do their best to make conclusions supported in data. Yes, data and measurements will always contain error, but...

      The Media must stop compounding error with faulty self extrapolations and misinterpretations based on data that already has minor error and conclusions based on single studies. I believe in the First Amendment, but I believe anything based on science always must be cited with at least a peer reviewed article link... etc.

        I can think of a million ways to photographically depict the vastness of space other than using one which will make most people think you're depicting the very thing that you say they didn't want to show. Sorry, your explanation fails the test of logic. I think the editor invested all of two minutes and twelve seconds thumbing through a photo stock collection, saw this one, wasn't smart enough to realize this wasn't a meteor shower, and used it in an attempt to depict a meteor shower. My reason for even bringing it up is not to point out the difference between time lapse star trails and meteorites, but to illustrate how even professional science writers/editors don't understand some of the basic principles of science. And to lay the blame on the sorry state of education these days.

      Do you wait for opportunities to say things like this? What is your objective exactly, would you like the proceeding comments to be all about how smart you are? For the remaining questions to be directed at you about how CNN could have made this article better? Whoever wrote this probably submitted it and an art editor attached the picture later. Little did he know he would he would arouse the wrath of a pretentious little know-it-all who has nothing better to do than to leave snide comments about an out of place picture which did nothing to detract from the article. The art could have been a picture of a random scientist holding a beaker, who cares? The important thing was the title and content. You are obviously one of those people who have no friends in life and believe its because no one is good enough to be your friend but in actuality its jus because you're unpleasant to be around.

        Wow, just wow. The spiteful jealousy seeping off your post is really something. Clearly the people that you claim to be "know it all's" understand this article a lot better than you, and I personally appreciate them commenting on the errors made by CNN. The picture should have meaning to what the message in the article is trying to get across. You know, as well as I know, that the picture was supposed to depict a meteor shower - not just a random space picture. This is not the 3rd grade. Imagine that a huge southern California forest fire occurred and CNN wrote about it. Would they throw up a random picture of fire without the burning forest? No. Why? Because most people know what a forest fire looks like and would want to see not just flames but a burning forest on top of the article. This creates sensationalism and that is how they get half their readers in the first place. This leads me to the people who would know that the pseudo meteor shower is actually a time-lapse. This group is minute, probably made up of either scientist of some sort and or intellectuals whom enjoy the topic. If you knew a topic well and became excited for this pseudo breakthrough in evolution, would you not get a tinge upset at how misleading the whole article seems to be? Also, why do you not want to know the real truth of the article? Enjoy living in deep ignorance much? I know i don't. So, yes the picture is wrong; as well as the misleading title - and I thank the intellectuals that study this topic, for they actually taught me something; whereas this article did not. Alas, have some humility to admit that they are right and that you do not know much about the topic at hand. Yes, you are right that not everyone knows everything, but what I really wonder is: how did you come to that conclusion with the comments on here? Just because you do not know much about space - does not mean you are dumb. So, relax; take a breather...and have a nice day. 🙂

    "DNA discovered in meteorites"

    Wrong.

    DNA has not been discovered in meteorites. Instead, simple and very boring purine and pyrimidine bases have been discovered.

    We have known since the Urey Miller experiment in the 1950s that such molecules could be formed before the emergence of life on primitive Earth, e.g. in the presence of lightning.

    This "discovery" really isn't very interesting at all. The molecules don't even have optical activity. Some months ago there was a similar fuss when glycine (achiral amino acid) was discovered on a comet. Another boring small molecule with no optical activity. Wake me up when they find a meteorite which contains molecules that have optical activity.

      The headline said "DNA" was discovered in meteorites, although the article quickly made it clear that was not what was found. However, it is usually editors, not story writers, who write the headlines, so I do not blame the writer. When I saw the headline, I figured they just found purines, pyrimidines and racimic mixtures of sugars. If they had found any intact DNA of extraterrestrial origin, this would be a much larger story.

      August 12, 2011 at 12:21 am |
    • Alex

      What does the fact that a molecule is achiral or chiral have to do with its importance in the origins of life? Glycine is an essential amino acid so I don't understand why it's discovery in some extraterrestrial context would be any more "boring" than some amino acid that is chiral.

      >>"Check your references. DNA nucleotides have been identified before. This is not a new discovery unless there's information I’m missing in this article"

      I believe the difference is that they feel they have evidence that the DNA found was not due to contamination from terrestrial sources. The NASA article agrees with you in that DNA has been found before; however, the earlier finds could not be proven to *not* come from terrestrial contamination.
