PSY398H5 Lecture Notes - Lecture 4: Sexual Reproduction, Secondary Sex Characteristic, Biological Specificity
Document Summary
What is adaptive about social behaviour? (i. e. , ultimate causation) We have evolved in a way that reproduction depends on social components there are benefits of sexual reproduction there is a cooperative advantages. Affiliative: brings animals together affiliative components of behaviour. Aggressive: keeps animals apart also a type of social behaviour, but it keeps them apart thats the goal to establish certain boundaries for social behaviour. Other motivated behaviours are secondary to this goal. o o i. e. eating, drinking, social affiliation (etc. ) enable the organism to achieve reproductive status. in animals, a lot of species engage in this kind of behaviour directly for reproduction. Organisms are naturally selected with proximate mechanisms that enabled reproductive success in their ancestors. Slide 6: males/females and their morphology and how they engage in it. Reproductive behaviour is a consequence of proximate mechanisms that have been selected for. Intent for self-perpetuation is not necessary. o organisms have by-pass this intend.
