In The Evolution of Desire by David M. Buss, many different accounts of studies aimed at understanding sexual conflict in relationships are reviewed. This research gives insights into understanding human mating behavior. Buss uses advances in evolutionary psychology and describes the major findings in sociobiology as well. Mating behaviors of humans can lead one to be stupefied and at the same time can be extremely astonishing. The theory described in chapter seven, which is titled Sexual Conflicts, is the accumulative of three extraordinary and groundbreaking studies taken place in the twentieth century. In this chapter Buss describes the conflicts many humans undergo in sexual accessibility, emotional commitment, and the investment of resources. The strategies of mating humans that have developed through time have also become the strategies that allow our race to reproduce and survive. The first study was in 1948 by the geneticist AJ Bateman. In this study it is assumed that Darwinian evolution’s main emphasis is to pass genes on. Bateman examines and studies the fruit fly’s mating strategies and provides a foundation for explaining mating strategies and applies it to humans. Basically the success of a male fruit flies reproduction is limited by the amount of chances to mate. Whereas the female fruit flies success in reproduction depends on their physical capacity to become impregnated. For example, if male and female fruit fly have the opportunity to mate one hundred times a day with different partners respectively, but the female becomes pregnant on the fourth try, the rest of the ninety-six attempts were only for pleasure. Males have the opportunity to pass on genes every time but females become pregnant and do not have that ability. The next study relates strictly to the amount of contribution to parental investment 1

done by Robert Trivers in 1972. The emphasis is on sexual selection and the amount of investment contributed by the parents creates competition. He distinguishes that Bateman made a mistake by leaving out the amount of investment the parents will make raising the young. He modifies the study to include that the mother will usually invest more in raising the offspring. Therefore the father figure has less parental investment in the upbringing their children. It can be assumed that females are more nurturing due to the nature of the womb, while men are more susceptible to competition, combat, and aggression. Buss later makes a case that women make a bigger parental investment and commitment because they must search for mates who are willing to commit to a long- term relationship. The third major influence on this chapter was a study taken in 1988 by Martin Daly and Margo Wilson. The study provides the so called groundwork for Dr. Buss’s The Evolution of Desire. It showed that whoever is smaller in the relationship, either female or male; the smaller individual has the larger parental investment and can be seen throughout different species. They divide the subjects into three different groups of
