| Chimps | closest relations to humans fission fusion mating system- males and females live separately and come together to mate (temporary during mating), eat fruit, leaves, insects, and meat-hunting behavior similar to ours use tools, live by learning/culture |
| Gorillas | largest primates sexually dimorphic females birth every 4 years, when males sexually mature, silver back appears, black back before infanticide among silver backs common eat fruit, and plants |
