Reuse of key genes is a common theme Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one. But biologists treasure these small fish for what they are revealing about the genetic changes that drive evolution. Now, researchers have sequenced the stickleback genome for the first time, and they have discovered that as fish in different parts of the world adapted to live in fresh water, the same sites in the genome were changed time and...

Humans are clearly different from chimpanzees. The question is, why? According to researchers at the Stanford University School of Medicine, it may boil down in part to what we don't have, rather than what we do.

Understanding these and other...
