Chimps 'more evolved' than humans

Humans, it seems, have been taken down a notch or rung on the evolutionary ladder!
Chimpanzees are the more highly evolved species, according to new research.

The research team found that 233 chimp genes, compared with only 154 human ones, have been changed by selection since chimps and humans split from their common ancestor about 6 million years ago.
