By the way the coelacanth isn't THAT surprising, just look at sharks, that species is also over 100 million years old. It just means that their situation hasn't changed that much and that they've been adapted well enough to not need change that much.



Another Q. Is it adaptation that causes variation or mutations? I species cant mutate willingly, can it? A mutation happens by itself. Then why is it that 'they did not have the need to change'? In 100 million years alot has supposed to have happened right? Then why is there not even the slightest change?
