"The DNA Code" - New Research Shows Life Hardwired in the Universe

Ch2201A recent mathematical analysis says that life as we know it is written into the laws of reality. DNA is built from a set of twenty amino acids - the first ten of those can create simple prebiotic life, and now it seems that those ten are thermodynamically destined to occur wherever they can.

For those unfamiliar with thermodynamics, it's the Big Brother of all energy equations and science itself. You can apply quantum mechanics at certain scales, and Newtonian mechanics work at the right speeds, but if Thermodynamics says something then everyone listens. An energy analysis by Professors Pudritz and Higgs of McMaster University shows that the first ten amino acids are likely to form at relatively low temperatures and pressures, and the calculated odds of formation match the concentrations of these life-chemicals found in meteorite samples.

They also match those in simulations of early Earth, and most critically, those simulations were performed by other people. The implications are staggering: good news for anyone worried about how we're alone, and bad news for anyone who demands some kind of "Designer" to put life together - it seems that physics can assemble the organic jigsaw all by itself, thank you very much, and has probably done so throughout space since the beginning of everything.

The study indicates that you don't need a miracle to arrive at the chemical cocktail for early life, just a decently large asteroid with the right components. That's all. The entire universe could be stuffed with life, from the earliest prebiotic protein-a-likes to fully DNAed descendants. The path from one to the other is long, but we've had thirteen and a half billion years so far and it's happened at least once.

The other ten amino acids aren't as easy to form, but they'll still turn up - and the process of "stepwise evolution" means that once the simpler systems work, they can grab the rarer "epic drops" of more sophisticated chemicals as they occur - kind of a World of Lifecraft except you literally get a life when you play. And once even the most sophisticated structure is part of a replicating organism, there's plenty to go round. Source

One thing I'd like to do before I die is create a unique bacteria or germ out of rare materials. I doubt it will happen but I did make two sons. That's right! I knocked the boots off that ho. Ho bein' my wife.

Why not a daughter and son having the best of both worlds. You're cheating yourself out of a lot of action and fun lol.

Well, I was goin' for a daughter but got the 2nd son instead. The wife got her tubes tied so I'll have to knock someone else up.
