Document Summary
Adaptive value of a sexual behaviour: would be nice to know how sexual behaviour evolved o. 4 avenues of evidence into sexual behaviour of hominins: application of general principles of sexual selection into the fossil record. Difference physical variables that play into aspects of sexual behaviour. Goes hand in hand with behaviours and relations between the sexes o. Protein and hormonal content to extract behaviours: analogies based on human hunter-gatherers. Based off traditional human societies: hominin behavioral reconstructions from extant primate behaviour. Based on living primate groups to find out reproductive behaviour in early human ancestors. Most studies based on sexual dimorphism: different in traits between sexes. Bigger canines tend to relate to male aggression: males can be 2-3 times the size of fertile females. Increase body size to compete to have sexual access to a number of females. Sex dimorphism is related to male to male competition o. Exclusive sexual access to a number of fertile females.
