Dual inheritance theory refers to the idea that both genetic and cultural factors contribute to the development of human behavior. This theory is sometimes referred to as gene-culture coevolution, cultural evolution theory, or biocultural evolution theory. It is also related to niche construction theory, which suggests that organisms actively modify their environment and create cultural practices that shape their development. In some contexts, the theory is linked to the study of gene expression and epigenetics, which explores how environmental factors influence genetic expression and lead to changes in behavior. Ultimately, the theory seeks to explain how human biology and culture interact to shape the evolution of our species.
