Jeremy:
I agree Grant and I was mentioning crocs to illustrate that, in some cases,
the process of evolution had halted at the point of perfection.
Crocs are truly one of the most perfectly adapted animals in the world.
They fit into their environment so well that there has been no disadvantage
in protracted stability. Maybe the ones that 'changed' were the ones which
died. If this is the case, I would assume that if their environment did
change rapidly they would either die out or commence the process again.
I freely admit that I have no great knowledge of genetics or evolution and
welcome your input.
Cheers
