How did life start? No creationists please

Thanks Chuck - I'll try to dig out that Nature.
Also - thanks for the belly laugh in your response to JesusisAlive. (June 18, 2013 at 2:44 am)JesusIsAlive Wrote:(June 16, 2013 at 10:51 am)Rationalman Wrote: How do you think life on earth started? What do you believe? No explanations involving deities please. Do you believe in Abiogenesis or something else? e.g. My grandfather believes we were created by an advanced race of aliens. So uh...do you actually have a brain of your own, or do you just have a tape recorder of your local evangelist megachurch preacher's favorite sermons on loop in your skull?

You can fix ignorance, you can't fix stupid. Tinkety Tonk and down with the Nazis. Quote:God saw everything that He had made, and it was very good. But soon the picture darkened. God must have known before hand that it would, That makes your god out to be something of an incompetent fuckhead. Why worship such a fallible being? What is wrong with you? RE: How did life start?

One favorite hypothesis is complex multi-cellular life, from the point of view of energy budget, is not favored unless it can exist in an ecosystem where the food chain is enriched in energy made possible by oxygen respiration. Oxygen respiration can't happen unless there is free oxygen in the atmosphere. Free oxygen can not easily exist in earth's atmosphere because oxygen is highly reactive and chemical reaction with rocks would rapidly scrub any oxygen that is in the atmosphere, unless something is continuously replenishing the atmosphere with free oxygen. The only agent that continuously and copiously replenishes the atmosphere with free oxygen is cyanobacteria. Cyanobacteria evolved 2.6 billion years ago, and reached the abundance to turn the earth's atmosphere from chemically reducing to chemically oxidizing 2.4 billion years ago. Initial steps towards multicellularity can happen before 2.4 billion years ago, but since multiceullarity didn't pay from energy budget perspective in a reducing atmosphere, the complete evolution to full blown multi-cellularity didn't happen so long as atmosphere remained reduing. Only after the great oxygenation event 2.4 billion years ago was the condition favorable towards complete evolution of full blown multi-cellularity. It is true that the earliest totally unequivacal evidence of multicellularity dates to 1.4 billion years later, during the late neoprotozoic era 1 billion - 540 million years ago. But it is tentalizing that the first hint of multicellularity dates to 2.1 billion years ago, just 300 million years after it is thought that conditions on earth first made multicellularity a profitable mode of existence.

God saw everything that He had made, and it was very good. But soon the picture darkened. God must have known before hand that it would, and some have regarded his whole work of the creation of man as but a step toward the glorious world that will yet issue from it, as toldvin the closing chapter of Revelation. Read your Bibles. It is essential that you do. This means omnipotence and omniscience, far from being some overarching cosmological quality, is in fact an mundane artifact of just that 2% of DNA that makes christ different from chimp. I always knew there was very little to omnipotence and omnicience. RE: How did life start? No creationists please

Who created them>who created them>who created them... endless cycle. It ends whit big bang. But where matter came from and Who driggered explosion? How from this explosion whit unimaginable heat and presure fragile biological body and consciousness and subconsciousness whit its infinite depth of thoughts and desires came to life?
On the subject of only 2% DNA variation between us and Chimps. Chimps are genetically closer to us than they are to Gorillas.
Now that is startling - isn't it? RE: How did life start? No creationists please

Not if you've seen how pantacostals at revival meetings would howl like chimps instead of comporting themselves with stately dignity like gorillas.

If the idea is that we look at a complex object and recognize design, then compare the two: a bunch of rocks and a stick of dynamite, or the most complex being that has ever existed by orders of magnitude. You think the latter is more likely to not have a designer?
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
