Interplay between Cultural Evolution and Biological Evolution in Our Species

Knowledge on various aspects of human culture has enhanced. The outcome of such knowledge remains in the domain of social sciences. Biologists could use such information of culture to explain human evolution in terms of interplay between the gene and culture. Collective brain, cooperation, social learning, and genetic endowments contribute to cumulative cultural evolution. Our uniqueness is due to our biology and culture. Gene, brain, hormone and the environment governs the biological and cultural evolutions. Interactions between the biology and culture are well-known. However, the role of cultural evolution in our species is still underrepresented in biological sciences. In such situations, the emergence of disciplines like cultural genomics, cultural neuroscience could reveal interesting facts of human evolution. Here, I briefed the theoretical aspects of human culture including the cultural traits and system, role of high-fidelity transmission in cumulative cultural evolution, cultural group selection and cultural
filters. I have portrayed classic examples of gene-culture interaction to illustrate the interplay between cultural evolution and biological evolution. Newly emerged disciplines combing the knowledge of biology and culture have also been briefed to update our understanding of evolution our species in a holistic way.
