Answer:
Biological anthropology shows that cultural contexts are useful to explain human evolution.
Explanation:
Biological anthropology is a research area focused on the study of biological and behavioral determinants associated with human evolution. Biological anthropology enables us to trace the evolutionary origins of hominids and primates in general. Moreover, this discipline also sheds light on how different environments act on the mechanism of natural selection and thus shape human behavior. However, biological anthropology should not be considered to be part of social Darwinism used to apply Darwin's ideas to social policies.
