Document Summary

Function of estrus is not simply to get sperm and conceive; males motivated to seek out females (cid:224) females most discriminate during estrus: dominant or competitive males pronghorn antelope, asian elephants, american bison, chimpanzees, large, robust males red deer, guinea pigs, testosterone facilitated traits asian elephants, rhesus macaques, symmetrical males snow voles, mhc compatibility house mice, eg/ chimpanzees females promiscuous; sexually receptive 10/30 days in cycle, least promiscuous during fertile 2 3/10 days; prefer dominant males. Symmetry thought to be a good indicator of good genes and low mutation load; heritable: human body plan; same genes code left and right sides (cid:224) absence of perturbations (toxins, pathogens, radiation, trauma, mutation) should develop perfect bilaterally symmetry, developmental processes buffer effects of perturbations (maintain symmetry) (cid:224) high mutation load = less able to buffer perturbation = asymmetry, 10 traits = ear length, ear width, each of 4 fingers, wrist width, elbow width, ankle width, foot width, total asymmetry score =
