Document Summary
Biological basis of social behaviour: we are born "prewired" or predisposed to behave. Evolutionary theory 1: natural selection -well equipped to cope with environmental challenges to survival. Genetic environment: biological structure we receive for this purpose. Different species have different genetic makeups according to their environmental needs. The most fit species to meet environmental challenges are the ones that will. The most adaptive characteritics within species will prevail thus strengthening own species in the long run through reproduction of the fittest. Ex/weak ones not able to secure a partner will have low reproduction success so genetic pool will be geared to having stronger children because stronger males survive. Today is high intelligence so greater likliehood at graduating and making money so will be healthier and live better off. How are organisms predisposed for social behaviour? simple stereotyped actions that are activated by certain quite: fixed action patterns- specific stimuli.
