Study Notes
Evolutionary Theory of Parental Investment and Sexual Selection
- Sexual intercourse can lead to a 9-month investment for women, including breastfeeding that can last up to 4 years.
- In some species, males invest more in reproduction, leading to female competition for high-investing males.
- Among mammals and primates, females undergo internal fertilization and gestation, resulting in significant parental investment.
- Women's evolutionary past led to selective mating behavior due to the risks and costs associated with investing in offspring.
- Trivers's theory predicts that the sex investing more in offspring will be more selective about mating.
- Both men and women invest heavily in children for long-term mating, leading to choosiness in mate selection.
- Evolutionary psychology suggests that ancestral women preferred generous men as they aided in survival and reproductive success.
- Men vary in numerous characteristics relevant to mate selection, and women's preferences evolved to prioritize adaptively valuable traits.
- Mate seekers gauge a prospective partner's future potential in addition to their current attributes.
- Women's preferences track critical components of a man's value as a mate, but assessing a man's true qualities can be challenging.
- Psychological mechanisms are necessary for women to evaluate and integrate knowledge about a prospective mate to make a final decision.
- Selecting a mate requires the ability to weigh relevant attributes and integrate knowledge for the final decision.
