00:07All life on Earth is related, and evolution helps us not just understand who's related to whom,
00:12but how we got to where we are and why we are the way we are.
00:35The game of life is all about reproduction.
00:37From bizarre to beautiful.

00:49And transform cloning into courtship.
00:52The primary function for a feather like this is, well, sexiness.
