Describe one assumption of the biological approach.

• Point

  One assumption of the biological approach is that human behaviour has been shaped by evolutionary influences. This means that behaviours we exhibit today have developed over millions of years because they were adaptive for survival and reproduction.
• Evidence

  The theory of natural selection, proposed by Darwin, explains that behaviours which enhance an individual‘s survival and reproductive success are passed down through generations. for example, altruistic behaviour, such as parents risking their lives to protect their offspring, increases the chances of survival in their genes
• Explain

  The concept of the environment evolutionary adaptiveness (EEA) helps to explain why certain traits have developed. For instance, the human brain has evolved to be large relative to body size due to the demands of complex social interactions, which were crucial for survival in early human societies. Those who were better at forming alliances and relationships had a higher chance of survival.
• Link

  This assumption supports the idea that human behaviour is deeply rooted in biology and evolution, suggesting that many psychological traits exist because they helped our ancestors survive in their environment.
