Document Summary
Feb 10 2017: monkeys are more like us than we think therefore we can learn a lot from them. Inlike orangutans, early hominins probably lived in multi-male, multi-female groups: food sharing may have been important to early hominins (especially mother- offspirng, as in chimpanzees) In men, peak production isn"t until age 35. The distribution of food effects on social system: food is generally not evenly distributed, there is variation in the density of food patches (eg. fruit trees) and also distance between food patches. It provides an effective vehicle for transmission o disease and pathogens. Chimps use tools: rocks-breaking nuts open, modified stick- to extract termites, leaves- balled up to make sponges for drinking water, sharpened sticks- hunting, sticks- break open bee hives. Feb 10 2017: sticks- to test depth of water, detached sticks used for support in swampy areas. Nwm use tools: capuchin monkey use sticks to retrieve food, use rocks to process foods.
