This wasn't a post to say evolution is invalid, it was more to the point that diverse life appeared at once.., Those factors you mentioned have little revelancy to the fact that these fossils have been found all over the world, and although the subtle variance in like species the basic blueprint of differing structures took place all over the planet.., The subject of algae you speak of including the bacteria and so forth is part of it but it's not saying evolution is false just the way it may of happened, as suggested instead of there being 1 common ancestor, that there was a field of ancestors, but all at once (not abracadabra once), geologocially speaking. Also, that's the question as to why we don't have no trace of transitional fossils at this stage, when we have identified embryos of microscopic level and soft tissue, prior to the cambrian fossils, but no transitional fossils from single cellular to the many multicellular species that inhabitated the water around the world at once. The evolution Phylum theory still remains quite reasonably true, but it just wasn't one phylum, but a field!! It doesn't mean the transitions didn't happen, but the information and evidence points differently."Nobody really understands how this happened..." -referring to the Cambrian explosion.
- Wrong. Scientists have very good theories on exactly what happened to produce such diversity in such a relatively short period of time.
- algea from the oceans produced more oxygen, more oxygen was absorbed into the atmosphere creating the ozone layer (O3), which deflected UV rays from the sun, allowing life to take off and diversify. More organisms led to more environmental competition, which led to natural selection. The environment, along with the already rich body of critters with teeth and claws running around produced rapid evolution. The fact we don't have fossil evidence of a lot of the transitions between pre-cambrian organisms and post-cambrian organisms doesn't mean it didn't happen. The conditions of earth during that time might have been hostile to the formation of fossils. We know today that it is extremely difficult for a fossil to form, and even rarer for someone to find it. Of every human being living in America today (that's over 330 million), statisticly if we all dropped dead today, less than one complete human skeleton would become fossilized. The fact we have any fossils is amazing.
"Darwin expected it to happen slowly..."
- Awesome! Darwin also might have expected to have a full head of hair in his old age..., Darwins expectations regarding his theory don't falsify the evidence in any way.
I've watched a little over halve of the full length movie, and it goes into detail of how the information must be passed along through the membrane of the cell (before DNA plays a role) within the single cell, which begins it's mutation into the more complex multicellular organisms.., And that is the ponder now as to where this information must have come from ie. ID, or if not through selective transitional mutations (which are not evident, yet). I would have posted the movie as well but, it hasn't been put up on the web and is only available by DVD now. I just happened to catch it on t.v. last night scrolling and began looking into it further.
Darwin's Dilemma: the Cambrian explosion
The information I watched looked pretty solid, although I have seen from both sides of the arguements through researching, of people making non-sensical statements and assumptions with regards to the information, while disallowing competent reasoning and logic within the components of the evidence provided. (ie. everybody sticking to their faith)
