Natural Selection
Elmer writes:
Another way of looking at the question raised in the OP is this--If Natural Selection is true, then why aren't humans the only species of primate extant? Put another way, why is it that anything besides archaea exist?
That is an excellent question.

That is, any bioform/genotype differing from the best, the ideal, must be 'weeded out' by 'natural selection' with each new generation. The difficulty with this notion being that in fact, no such thing actually happens in the real world, because "Natural Selection" is a local, not a universal, phenomenon.
And you have given yourself an excellent answer.
Which is why the notion of "NS" as the supplier of this requirement persists, even though the fact of biodiversity shows, as above, that "NS" events are every bit as relative, local, irregular, unpredictable, anomalous and chance-based as any random genetic mutation.
Your kidding right?
  • Unpredictable? Tell me what happens to a brown rabbit in the winter
  • anomalous? See above
  • chance based? see above
    Biodiversity shows that there is a diversity of environments. Environments can change in unpredictable and irregular ways so its no suprise to say that natural selection is also irregular (so I would agree with that point, along with relative and local)
