> dhw: Thank you, your point is well argued too, except that it's the wrong point. If homo sapiens was the pre-planned goal of evolution, and chimps and humans branched off from a common ancestor, what was the point of the chimp branch of the bush? Of course our brain and posture didn't have to happen.-You still miss my point. If the UI set up evolution to complexify and reach us, as I propose, then complexity will come with a bush of life and we will apper as the pinnacle of the bush, with lots of branches. The tremendous evidence of convergence makes that point. -> dhw:Yes, we are unique, but so is the platypus, the last surviving member of its family. If only we could speak Platypan, it might even tell us that its presence on Planet Earth and its absolute uniqueness prove that it was the goal of evolution. My point is that the higgledy-piggledy bush is the exact opposite of what we would expect from a designed process with a pre-planned purpose. -Of course it is h-p, striving for complexity in many directions, not a straight course to us. If the UI in its wisdom wanted that approach, that is what we would see. But we don't see that. We must adhere to what we see, in judging the teleology. Bush it is. I've personally seen a platypus in Australia. We are much more complex. The poor fellow has to hatch eggs!-Was there some degree of guidance? Yes. Again my example of the apes staying apes and doing just fine and us charging off with big heads, fully upright. There was no Darwinian reason for that to happen, but it did. We are different in kind, not degree. Difference iby degree is not defensable. By my analysis we not be in the primate family, but a new human family. The Darwin classification is old and by the new findings, wrong. Why stick to ideas 150 yearw old?
