Final answer:
To say humans are biocultural organisms acknowledges that both biology and culture influence human behavior. This concept is supported by the biocultural approach in anthropology, which sees human evolution and culture as interlinked.
Step-by-step explanation:
To emphasize that human beings are biocultural organisms means that human biology and culture both contribute to human behavior, and that human biology makes culture possible while human culture aids in the survival of humans biologically. Thus, both statements a and b are correct in this context. The biocultural approach to anthropology highlights the interconnections between our biological systems and cultural practices, asserting that biological evolution has informed human development, which includes adaptations that have made culture possible. Culture, on the other hand, has influenced human choices which have impacted biology, such as dietary preferences affecting health over generations. Consequently, understanding human behavior requires a dual acknowledgment of our instinctual, biological drives as well as the cultural and environmental influences that shape these behaviors.
