Document Summary
Evolutionary psychology: humans evolved over millions of years, the human gene pool contains genes that were adaptive during evolution. Hunter-gatherer societies in the african savannah: more adaptive genes should be more prevalent in the gene pool, adaptation is a slow process. Genes that were adaptive may no longer be adaptive today: evolution and gender. Many evolutionary problems are the same for men and women. Those genes are selected equally for the genders. Some evolutionary problems differ between men and women. Gender differences: desired time before having sex. After 5 yrs no difference between genders: the evolutionary explanation. Men and women differ in minimal parental investment. Men can father hundreds of children in a life time. Genghis khan --> 1 to 6 asians can be traced to his relatives.
