Dual Inheritance Theory
Dual Inheritance Theory, also known as Gene-Culture Coevolution, posits that human behavior and societal development are shaped by two interconnected systems: biological evolution (genes) and cultural evolution (learned behaviors and ideas). While our genes influence instincts and physical traits, culture—such as language, traditions, and social norms—plays a vital role in shaping how we live. Both systems interact, affecting each other over generations, meaning our genetic makeup can be influenced by cultural choices, and vice versa. This theory helps explain human diversity and adaptability in various environments.

Dual inheritance theory suggests that human behavior and culture are influenced by two intertwined systems: genetic evolution and cultural evolution. This means that, alongside our biological inheritance from our ancestors, we also inherit cultural knowledge, practices, and norms from our social environments. Both genetic and cultural factors shape who we are, how we think, and how we behave. The theory highlights that cultural changes can happen rapidly, sometimes outpacing genetic changes, leading to complex interactions between our biological traits and the cultures we live in.
