No doubt those biological factors do play enabling in determinants human behaviour. Biological factors basically set the limits but our behaviour is more complex then the behaviour of animal.
- Major reason for the complexity is the role of culture to regulate human behaviour.
- We can explain the concept with the help of two example hunger is a basic need of human beings as well as of animals but the way this need is gratified by human beings is extremely complex.
Different people in different cultures eat different things in a different manner e.g. directly with hand or with the help of spoons, forks and knives.
- Sexual behaviour can be taken as another example sex is a physiological need. The structure and functioning is determinant by biological mechanism but it expression is different in different culture.
- At the human level, we find evidence for a dual inheritance theory. Biological inheritance takes place through genes, while cultural inheritance takes place through memes.
- The former takes place in a “top-down” manner (i.e. from parents to children)., while the latter many also take place in a “bottom-up” manner (i.e. from children to parents). Dual inheritance theory also shows that although biological and cultural forces may involve different processes, they work as parallel forces, and interact with each other in offering explanation of an individuals behaviour.
