Finding the first indications of evolution into more advanced, embryonic development has proved difficult, however, both because of the organisms’ small size and soft structures

The louse fossil record is relatively sparse

Rival Anthropologists Donald Johanson and Richard Leakey Reunite after 30-Year Rift

On May 5 famed paleoanthropologists Donald Johanson and Richard Leakey convened at the American Museum of Natural History in New York City to discuss human origins. It is the first time Leakey and Johanson--longtime rivals--have shared a stage since a public falling out in 1981. Viewers in the live audience and those who tuned in to the webcast tweeted the discussion and uploaded photos to Facebook, so I decided to use Storify to document this historic event.
