Final answer:
Bicultural evolution encompasses the biological and cultural changes that took place during the evolution of modern humans.
Step-by-step explanation:
Bicultural evolution refers to the process of modern humans evolving from various ancestral populations and encompasses the biological and cultural changes that took place during this evolution.
Biological evolution includes the physical changes that occurred in our ancestors, such as changes in anatomy or genetic makeup, that allowed them to adapt to different environments. Cultural evolution, on the other hand, involves the development of behaviors, beliefs, and practices that were passed down through generations and helped humans thrive in their respective societies.
For example, the emergence of language and the development of tools and technologies are examples of cultural evolution.
