Document Summary
Different mating systems: monogamy o o. Two individuals raise offspring but may have epcs. How do we find animals? o o o. Direct fitness + indirect fitness = inclusive fitness. Kin selection theory: animals should help kind because it will increase their own indirect fitness. Parents: r= 0. 5; half siblings and everyone else: r=0. 25. The higher, the better it is to help. Eusociality - most complex social system! (eu = true) - share 3 traits: o o o. Reproductive castes are cared for by nonreproductive castes. There is overlap in generations (siblings help raise: most are insects o. Because of haplodiploidy, the sisters are super related -> lots of altruism: naked mole rats are eusocial! Cooperation - altruistic behaviour between unrelated individuals. Just capture an instant of behaviour (eg one-zero) Much less labour intensive but you don"t record everything. Patch models charnov"s marginal value theorem: decision: stay in patch until you can do better elsewhere o o.
