Explain human behavior/traits by examining the long term reproductive dis/advantages of said traits and behaviors. Any 2 humans are 99. 5% genetically similar, 0. 5% genetic variation. We have way more in common with other people than differences. Differences in environment are what drive the different phenotype. Fact: men and women differ in their willingness to engage in sexual activity. Jennifer lawrence and channing tatum walk around and ask people to have sex. Girls usually responded no to the stranger more men than women said yes. Men are quick to interpret attention like a smile as sexual intent.
