Clint Is Dead, Long Live Clint

Clint, the chimpanzee in this picture, died several months ago at a relatively young age of 24. But part of him lives on. Scientists chose him--or rather, his DNA--as the subject of their first attempt to sequence a complete chimpanzee genome. In the new issue of Nature, they've unveiled their first complete draft, and already Clint's legacy has offered some awesome insights into our own evolution.
