Chemists May Be Zeroing In On Chemical Reactions That Sparked the First Life (sciencemag.org) 121

sciencehabit quotes a report from Scientific Magazine: DNA is better known, but many researchers today believe that life on Earth got started with its cousin RNA, since that nucleic acid can act as both a repository of genetic information and a catalyst to speed up biochemical reactions. But those favoring this "RNA world" hypothesis have struggled for decades to explain how the molecule's four building blocks could have arisen from the simpler compounds present during our planet's early days. Now chemists have identified simple reactions that, using the raw materials on early Earth, can synthesize close cousins of all four building blocks. The resemblance isn't perfect, but it suggests scientists may be closing in on a plausible scenario for how life on Earth began. The study has been published in the journal Nature.

  • figuring out how life began would be a great boon to the reverse-engineering of, well, everything that came after.
    • Then we ourselves will become god. :)

      Actually, having an in-universe explanation for how something can plausibly happen while being consistent with understood physical phenomenon doesn't mean that a creator didn't do it in the first place... if it were created, it would only mean that it was created to include all of the necessary ingredients for its creation. This is only deceptive if you are expecting the existence of such a creator to be somehow falsifiable in the first place.

      I'm not going to try and convince you a creator exists.... b

    • As the thousands of man hours tick up higher and higher as we attempt to understand how to create life, it only re-enforces what the man on the street with basic common sense already knows: Life, including man, was designed by a Designer, not by accident. If it takes 100,000 man hours (already likely spent) figuring out how to create life, and a multi million dollar lab to create it, all that proves is that it requires intelligence and direction to create life, not random chance (I doubt that we will ever

  • Because I've been trying to pick up women in bars to help me demonstrate the chemical reaction that sparks life. They just don't seem to grasp the significance of the scientific breakthrough that we could make together. I'd be willing to share the prize money 50/50, no problem.

  • ... why did the random spontaneous generation of "life" apparently only occur 1 time in the history of the known universe. DNA analysis seems to indicate a common genesis for all known Terran life forms, why has there been no discovery of evidence for another bio-genesis event here on Earth? Is the known RNA/DNA based life the only possible form of life?

    • Since it's a low probability, the mean time between occurrences would be large. Whichever happened first would have time to spread and out-compete any other that might have arisen.
      • Yep, the probability is so low in fact that it is just a total SWAG theory and has never actually occurred at all, either in the lab under artificial, ideal circumstances, or in the wild. The Evolutionist argument that it must have happened once because we exist is flawed in that it excludes all other explanations, and an extra-dimensional alien being creating life on earth is much more likely than an impossible event of spontaneous generation, which was disproven centuries ago. The Evolutionists just exc

    • ... why did the random spontaneous generation of "life" apparently only occur 1 time in the history of the known universe.

      We have only closely examined one planetary system (actually, the one we live in), which gives us a 100% hit rate for planetary systems being hosts to life.

      DNA analysis seems to indicate a common genesis for all known Terran life forms,

      It seems to, yes. But since we've only been looking for other systems for at best a couple of (scientist) generations, it remains possible that there are

  • I'd like to see some of you try to refute Dr. Missler's observations and analysis... I've been reading and studying for 30 years and find his work revelatory.

    I'd LOVE to see some of you realize that there are things going on with our universe that science will just never explain. "The wisdom of men is foolishness to God, and the wisdom of God is

    • Ive come to the conclusion that the late preaching on /. Is just the response from an underrepresented community in fear of H1B visa workers, community who in the midst of the cognitive dissonance and their political fuck ups, decide to turn into God and preaching in order to be more like those Indian guys that believe such funky shit, because maybe thats their secret.

      • My God is rational and logical. (Where do you think logic and mathematics comes from in the first place? It is inherent to the existence of the universe.) He created a universe filled with laws that can be observed and understood, both physical laws and moral laws (where do those laws come from, by the way, if there is no Creator?). If you violate either, there are consequences, whether you like it or not. That is the harmony of my worldview as an applied scientist. You seem to harbor a false sense of
