I'll just throw you an example.
A deer is born from a momma deer. He is normal in every single way, except he has better than average hearing and worse than average sight. His sibling is all normal.
One day when he is young, a huge volcano erupts and forces his mother, brother, and self to relocate to a new location, and other animals from the surrounding area as well. The volcano's ash blocks the sun a little, lessening visibility. Now, sight is no longer as important bc nobody can see that well anymore.
The momma deer continues to raise her babies, but the sibling of our baby deer gets picked off when he can't see a sneaky wolf coming for him. Our baby, with his superior hearing, laid low in the grass bc he heard the wolf from a long way away. Momma comes back and finds only one baby, which she raises to completion.
As an adult, the world around the deer is still darkened by ash blocking the sun. Visibility is still reduced. Therefore he is more fit to live in this new world than his "normal" kin. He will go on to live longer and have more babies, some of which will carry his hearing trait and themselves be better off.
Do you see how that works? That is just one generation (given, in a cataclysmic scenario that makes evolution more likely). There have been literally millions of generations.
This is a time scale that you and I really have no reference for. We can't relate to it. Nothing alive can. It's simply too much time.
PS: I doubt your cat can use his wild thumbs opposably, but it's still cool that he has that many digits
:doh: You JUST undid all your speculation above :doh:
