Dual inheritance theory
- Dual Inheritance Theory (DIT): An Overview**
Dual Inheritance Theory (DIT) is an evolutionary model that posits human behavior and culture are shaped by both genetic and cultural inheritance. Unlike theories focusing solely on genetics or culture, DIT integrates these elements, emphasizing their interaction.
- Core Principles:**
- Comparison with Memetics:**
DIT is narrower, focusing on humans and their biological interactions, whereas memetics broadly studies cultural transmission without specific biological ties.
- Key Researchers:**
Notable scholars include Robert Boyd, Peter Richerson, Joe Henrich, Richard McElreath, Kevin Laland, and Liane Gabora, underscoring the theory's academic backing.
- Criticisms:**
Critics argue DIT lacks detailed transmission mechanisms, relies heavily on evolutionary psychology, and needs better integration with social sciences like sociology and anthropology.
In summary, DIT offers a comprehensive view of human evolution by combining genetic and cultural influences, supported by prominent researchers but facing critiques for its scope and interdisciplinary integration.
