Document Summary
The science of behavioral biology: when several predictions derived from a hypothesis are shown to be true, the hypothesis gains credibility. The proximate and ultimate causes of monogamy in prairie voles: mouse-like mammal that lives in burrows in grasslands in the central parts of the u. s. and southern canada. Ultimate causes: by remaining with one female, male increases odds that he will father all that females offspring (adaptive value, result of modifications of a polygynous mating system (evolutionary history) 5:32:00 am: genetic differences among individuals differences in the way proximate mechanisms develop individuals to differ behaviorally ability to pass on their genes. 1/14/2018: evolutionary processes strongly linked to proximate causes. 1/14/2018 5:32:00 am displays: stereotyped actions used to communicate with others. Male may climb onto perch and release sex pheromone female smells this and pushes him off: so monogamy not because male"s interest but females. 2nd clutch slower males are at disadvantage.
