Biological evolution and cultural evolution are not mutually exclusive. On the contrary, they can influence each other. Genetically evolved human characteristics and abilities allowed for the accumulation and transmission of certain technologies, knowledge, behaviors, and environmental changes. These human-created conditions have in turn influenced our behavior, our body, our brain, and our genes throughout our evolutionary history.
Many biologists think that the following kinds of genes have probably spread in human populations due to selection by the social and cultural environment:
Genes that enable the digestion of certain foods (such as milk and dairy products, carbohydrate-rich foods, alcohol), with domestication and agriculture as cultural environmental factos acting as selection pressures
Genes that provide immunity against certain infectious diseases (e.g., malaria). Increasing population density, domestication and sedentary lifestyles increased the pressure from pathogens.
Genes that increase tolerance to hot and cold temperatures due to the spread of our species into new environments with different temperatures.
Genes that affect our outer phenotype (skin color, hair color and density, eye color, freckles) due to the spread of our species into new environments with different temperatures and/or through sexual selection
