Document Summary
11/1/16: chimps, use tool sets that may be task specific. Bonobo: make napkins, toothpick, swatter, scratcher, rain hat, branch dragging, nut cranking (but only found in sanctuary) Gorillas: do not need extractive foraging tools much in wild, but in captive settings will use tools, will use stick to probe in water when crossing to check depth. Culture (sensu lato) - shared belief systems, styles of dress, language rudimentary in some primates: orangutans can do kiss squeak, but there are actually distinct cultures with different methods of kiss squeaking. Things not in the genus homo: earliest hominins/lca, basic australopiths, except australopithecus sedeba, robust australopiths. Divergence appears after au. afarensis: radiation resulting from grassland expansion, homo lineage - more intelligence and tool use for generalized diet, paranthropus lineage - more anatomical specializations (megadonty) to adjust to diet of lower quality food. African dogs smaller, so try to eat and rip meat as fast as possible before hyenas and lions drive them away.
