Document Summary
Offspring are genetically unique (less likely to go extinct in unstable environment) More energy generally required to find a mate (internal fertilization) Vulnerable to predators (weak babies, weak pregnancy, long maturation) Bateman"s principle - female plays a significantly larger role in their offsprings reproductive success. Males are capable of producing many sex cells, while female sex cells require time and maintenance. Sexual selection - involves female choice; males have to act and look certain ways to attract females. Ex: bird feathers, peacocks, height in humans. Female choice - the term used for the selectivity displayed by females in choosing a mate because females often expend much more energy than males do in the production and care for the young. Sperm competition - selection can act on sperm morphology, sperm number, as well as female"s ability to control fertilization success. Human uniqueness - sexual behavior is more instinctively controlled among lower species and more controlled by the brain in higher species.
