Biological determinism

Biological determinism is the hypothesisthat biological factors such as an organism's individual genes (as opposed to social or environmental factors) completely determine how a systembehaves or changes over time.

Consider certain human behaviors, such as having a particular sexual orientation, committing murder, or writing poetry. A biological determinist would look only at innate factors, such as genetic makeup, in deciding whether or not a given person would exhibit these behaviors. They would ignore non-innate factors, such as social customsand expectations, education, and physical environment.

Very few scientists would wholly support the strong thesis of biological determinism. However, some may believe that biological factors primarily determine a system in normal environments. Biological determinism is used to explain basic instincts such as chicks following their mother or babies crying for food. Proponents of this more limited position are nonetheless frequently charged with supporting biological determinism.

Biological determinism is the opposite of social determinism.
