Document Summary

Carry genetic information in the form of dna. More often than not, multiple genes worth together. 95% differences within a race: evolution psychology. The main goal of organisms is to survive and reproduce. Any trait that helped our ancestors survive and reproduce are traits that modern humans display. Men tend to display more sexual behaviors than women. This indicates a difference in socialization, not a difference in levels of sexuality. Participants were told to approach attractive strangers and ask them to go to bed with them that night. Most men responded with an enthusiastic yes, not a single woman responded positively. Men and women have the same goal; survive and reproduce. Women contribute 9 months of their lives towards the development of a child, men contribute just 30 seconds. Females have to be choosy about their sexual partners to ensure that they are choosing a mate who will stick around and help raise and protect the offspring.
