Sorry, I could only get back to this now. I am a sole recalcitrant in a JW household with limited confidential access to a computer.
Slimboyfat: But reality shows that evolution tends toward similar forms all the time. It seems to have a deeps structure.
The articles you link in support appear to support your proposition, but are limp when looked at in detail. Yes birds and bats both have wings to fly (no surprise there) but look closely at the outlines of those wing structures. In birds, the fingers on the dinosaur hands have virtually disappeared, presumably to minimise weight. In bats, the fingers have become long spindly supports for the wing. In pterodactyls, you will see another wing structure again. Hence there is only limited convergence, at least as far as I can see.
I could make the same point about shark fins vs dolphin fins. So at this stage, I have to agree with Cofty on that one.
Slimboyfat: Intelligence itself seems to be the natural result of the process, not a random freak. So what does that tell us? What does it mean if the universe is actually built in such a way as to result in a brain which can understand it?
This is your better point. It certainly (to me at least) is one of the better arguments for a creator that I have ever heard. The universe has indeed resulted in a brain which understands (or tries to understand) it.
However, at the moment, I am not satisfied on the first assumption, ie that "Intelligence itself seems to be the natural result of the process, not a random freak." Some evolutionary processes are rare. Cofty points out that flight has evolved at least 3 times (I count 4), making it unusual. Only once has evolution produced a species (our ancestor, homo erectus around 100 million years ago) that learnt to use fire as a tool.
I would argue that when homo erectus learnt to use fire as a tool (giving it huge advantages but a need for a bigger brain), it meant there was a "natural selection" advantage in being bigger brained, more imaginative, more capable of planning, more capable of abstract thought, etc. (This is a big topic in itself.) This evolutionary outcome has only happened once in the history of life on Earth, and only comparatively recently, so it is not a "natural result".
Also, the proposition assumes that humans are somehow superior to all other life forms, solely on the basis that humans are more self aware, capable of conceptual thought and curious about the universe, is presumptuous. It could be that this self awareness is just a byproduct of our niche in nature.
Further, if as you speculate, that "Intelligence itself seems to be the natural result of the process, not a random freak." you still have to get around the "endless turtles" conundrum I referred to in an earlier post.
I hope this all makes sense. Feel free to ignore it if it doesn't.
