Descent with modification!

Read 'The Panda's Thumb"  by Stephen Jay Gould.  Or any of his books, for
that matter.

Basically, changes occur with modifications with what's already there.  As
for the panda, it has a 'thumb' that's evolved from a wrist bone or
something like that.  That's why cows will always be cows.
