Document Summary
Best analogs for the behaviour of our last common ancestor with apes. Each territory"s band is defended by 3-4 adult males. Each band has one or more family groups. One adult female and her offsprings (including males up to 10 yrs old) aka matrifocal group. Higher ranking females give confidences to their offsprings. Meaning a female in estrus will mate with any male she is comfy with. Differs from gorilla uni-male polygyny in which the largest silver-back male gets all the ladies. Termite fishing with a small twig or grass stem. Chewed leaves used as a sponge and as toilet paper. Cracking nuts with a stone or wood hammer. Seen chimps sharpen a stick to stab and kill a small mammal. One of the few examples of females engaging in hunting. Males engage in deliberate hunting using ambush strategies. All nearby chimps feed on the corpse at the same time.
