Document Summary
Predict animals forage in such a way: minimizes the costs and maximizes the benefits maximine reproductive success (fitness) So: how does altruistic behavior arises during evolution. William hamilton (1964): proposed that evolution does not distinguish between: genes from parent to offspring. Led him to idea of inclusive fitness=sum of: direct fitness= #alleles an animal passes on to its own offspring. 2. indirect fitness= common alleles of close relatives. Inherit same allele from a recent common ancestor coefficient for 2 unrelated animals=0 between parent and offspring = 0. 5 (share their alleles) between siblings = 0. 5 between cousin = 0. 125. Form of natural selection that increases fitness through breeding success of close relatives. In beldings ground squirrels most alarm calls given by females aiding close relatives. Population= group of potentially interbreeding organisms of same species. Changes in population size: population growth: evaluation of change in population.
