 Dear students, in this topic we shall discuss evolution and human culture. The human culture and certain social behaviors are due to expression of genes. Genes perpetuate by natural selection. So human culture is related to Tarvenian evolutionary theory. An irrational interpretation of genetic and evolutionary basis of human behavior may be misleading because it will justify the status quo in human society rationalizing social injustices and animal behavior of human. However, the human behavior has plasticity. It is not a rigid genetic model. Just as our anatomical features vary extensively, so do the inherent behaviors due to environmental effects. Just like environment intervenes in phenotypic expression of physical traits, it also affects the expression of behavioral traits. Dear students, animal behavior may not be plastic, but the human behavior is probably most plastic than any other animal. As humans have greater capacity for learning. In human, the control of instinctive behaviors is produced by certain cultural norms. When we call human behavior as plastic, it means that it is modified. And to modify it, human's natural or Darwinian view is controlled by genetic factors. But its plasticity shows that instinctive behavior can be controlled. And in the cultural history of humans, humans have made many structured societies in which human behavior has been controlled. These structured societies have laws, governments, institutions, cultural values, and religions. These institutions define what behavior is acceptable and what is not. Many instinctive behaviors may enhance an individual's Darwinian fitness, but they are considered unacceptable and prohibited by law. Actually, these are the social and cultural institutions which define values. And these values actually make the human behavior distinct and controlled than that of other animal societies. Animal society or human society may, the difference is that is because of values, not because of genetics.
