Genetic, Behavior and Culture

The DNA molecule has an essential role in physiology, phenotypic characteristics and disease in humans. The information related to physical attributes such as height, hair color, eye color,… inherited from parents are kept in DNA molecule and in recent Genetic studies it has been shown that genes not only have a role in shaping physical characteristics but also have a decisive role in behaviors such as: Sudden excitability, adventurous behavior, excitement, desire for new initiatives and psychological diseases such as: schizophrenia, manic depression and autism. Recently, in social, philosophical and psychological studies the role of genes in regulating brain as the only center which control human behavior has been widely discussed. The long standing hypothesis in human history under the name of "tabula rasa" has served as a model providing a mechanism describing human behavior. However, this hypothesis is no longer acceptable to many. As the understanding of the complex human brain has increased, researchers have been trying to discover mechanisms and hypotheses to explain the human brain.The presence of many cultures on earth and the existence of similarities among all cultures demonstrate that genetics has a major role in creation and growth of different cultures. The present article attempts to briefly describe the role of genetics in the field of human behavior and culture.
