The study, published online on January 28th in Current Biology , a Cell Press publication, enhances our understanding of our two closest living relatives, chimpanzees and the lesser-known bonobos, and may provide key insight into human evolution. Although chimpanzees and bonobos have a very close genetic relationship with each other, the two species display major differences in their physical appearance, behavior, and cognition. For example, when compared to chimpanzees, bonobos seem to be much more peaceful and easygoing, retaining juvenile levels of play as adults, exhibiting low levels of aggression towards one another, and being much more likely than adult chimpanzees to share resources. It has beenaggression towards one another, and being much more likely than adult chimpanzees to share resources....
