Step-by-step explanation:
Evolutionary theories explain the relationship between earth, biology, and culture. Evolution is the process of change in organisms over time. It involves mutation, natural selection, and speciation. Evolutionary theories can be applied to both biological and cultural changes. Cultural evolution, like biological evolution, has been marked by different phases. Anthropologists study how the environment has shaped human biology and culture. The biocultural approach to anthropology acknowledges the connections between culture and biology. The process of natural selection promotes traits and behaviors that increase an organism's chances of survival and reproduction. Evolution is responsible for the tremendous biological diversity on Earth today.
