I haven't had the chance to fully read it over yet, but there's a new paper in PLoS about chimpanzees sharing foods raided from local farmers, the behavior potentially showing some parallels with meat-sharing behaviors seen in other populations of chimpanzees. I'll soon write something a little more detailed, but I will say that I think the paper is a little out of order (materials and methods should come before the results and discussion/conclusion). Likewise, be sure to look at some of the criticisms and caveats introduced by other primate researchers in the comments section, especially about how what the chimpanzees may or may not understand about their crop raids.
