The non-human prelate is our closest relative, and to get a unwrap perceptiveness of our biological origins we study their behavior.

He proposed a theoretical frame accord way for explaining the behavior of animals which constitute of four causes. The first cause, proximal cause refers to the internal change in the animal that elicits a particular behavior.

Behavior is a product of the interaction between both(prenominal) genes and environment. The extent to which genes controls behavior differs from one behavior to the next. Each person is innately inborn with a different set of heritable traits found exclusively in that particular animal or species. While genetic change is a random process, natural selection chooses the more phenotypically fit opposed to individuals lacking these traits (Bernstein, 1999). Individuals genetically fit cause an increase in reproductive fitness.

Hormones atomic number 18 a proximal cause that regulates the reproductive success. Hormones such as testosterones stimulate the increment of secondary sex traits and raise the prospects for hostile and sexual behavior. Testosterone begins to give its restore in utero and can affect the brain and development. When gravid rhesus macaques m! onkey where injected with testosterone hormone, the fetuses resulted in an enlarge clitoris and virile behaviors (Berkovitch, 1999).
