Final answer:
Biocultural evolution refers to the interaction between biological factors and cultural practices in shaping human evolution, involving processes like natural selection and cultural adaptation.
Step-by-step explanation:
The term biocultural evolution refers to the interaction between biology and culture in human evolution. This encompasses how biological factors and cultural practices influence each other over time. Biological evolution, which is the process of change in the genetic composition of a population over generations through processes like mutation and natural selection, is a key component of biocultural evolution. Cultural evolution, on the other hand, describes the change in human cultural practices over time. These two types of evolution are interconnected; cultural practices can affect biological evolution, such as dietary habits influencing the development of lactose tolerance, while biological traits can influence cultural development, like the physical capability for speech enabling the creation of complex languages. The biocultural approach in anthropology analyzes these interactions to understand human evolution.
