Document Summary
Apes are actually very gentle and mostly eat leaves. *100: >1 means more terrestrial lifestyle, <1 means more arborial lifestyle, can make correlation between behaviors. If two animals have the same index, they may have the same personality or lifestyle: arm length+ leg length*100. Jumping & leaping- hopping and leaping: mostly small primates like uacari, tarsiers, sifaka. Brachiation- use of upper limbs to move around aka arm swinging; body suspended from forelimbs and they swing through trees: gibbons and spider monkeys do this well but most primates do this. Bipedalism- using only two lower limbs in locomotion; movement on two limbs; humans are the only ones who use this all the time: bonobo, primate characteristics relative to other mammals. The reason we have these characterizes (listed above) is because we adapted to life in an arboreal environment: dental characteristics, heterodont (mammals in general which mean different types of teeth, 4 types of teeth:
