Why Koalas Have Human Fingerprints  Some accuse evolution of
being pretty directionless. After all, the whole process
involves random genetic mutations. But if evolution is just a
toss of a million-sided die, why do so many animals turn out
eerily similar? Nope, it's not intelligent design. We take a
look at the creepy look-alikes brought on by what biologists
call "convergent evolution."  Could a koala frame you for a
crime? Probably not you, but it could certainly frame your
species. Koala fingerprints and human fingerprints are so alike
that experts can mistake one for the other. Which makes no
sense, since koalas and humans split off from each other between
125 and 150 million years ago. Our genetics haven't crossed over
since (although that would be one cute baby), we're not the same
size, we don't do the same things, and yet the pads of our
fingers look exactly alike. How did that happen?  Convergent
