Final answer:
Biological and cultural evolution of humans are interconnected and reciprocal, with biological evolution providing the foundation for the development of culture, and culture influencing the direction and pace of biological evolution.
Step-by-step explanation:
The relationship between biological and cultural evolution of humans is interconnected and reciprocal. Biological evolution provided the foundation for the development of culture, while culture influenced the direction and pace of biological evolution. For example, the emergence of language, a cultural innovation, facilitated the spread of new skills and behaviors that enhanced human survival and reproductive success. This reciprocal system of biocultural coevolution demonstrates the interplay between biology and culture in shaping the evolution of humans.
