The non-human primate is our closest relative, and to get a weaken perceptiveness of our biological origins we study their behavior. Ethologist Niko Tinbergen, observed animals in their pictorial conditions and manipulated those conditions to film how they respond. He proposed a theoretical frame attain 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. Proximal causes such(prenominal) as genics, hormonal chemical mechanism, neural mechanism and environmental conditions work to produce variation in primate behavior. Behavior is a product of the interaction between two genes and environment. The extent to which genes controls behavior differs from one b ehavior to the next. Each various(prenominal) is innately inseparable with a different set of inherited 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 ar a proximal cause that regulates the reproductive success. Hormones such as testosterones stimulate the increment of secondary sex traits and raise the prospects for assertive and sexual behavior. Tes tosterone begins to give its pretend in ut! ero and can affect the brain and development. When gravid rhesus macaques monkey where injected with testosterone hormone, the fetuses resulted in an overdone clitoris and virile behaviors (Berkovitch, 1999).
