This article explores how evolutionary thinking helps us understand culture and social behavior as extensions of human needs, not merely biological imperatives. It challenges outdated views of cultural evolution as a linear progression and highlights culture's role in human flourishing, including spiritual and emotional well-being, using examples like music and archaeological insights.
Evolutionary thinking offers a powerful lens through which to understand culture and social behavior. Rather than viewing culture as a random or purely symbolic phenomenon, it can be seen as an extension of human biology and needs, shaped by evolutionary pressures to enhance survival and flourishing.
Philosopher Daniel Dennett begins his book on religion with a story about an ant climbing a blade of grass, only to be eaten by a cow. Dennett explains this behavior as the result of a parasite manipulating the ant to complete its reproductive cycle inside the cow. He draws an analogy between this and religion, suggesting religion might be a kind of parasitic phenomenon.
However, this analogy is contested. Culture, unlike a parasite, serves human needs and is better understood as an extended phenotype — a concept where cultural artifacts and behaviors are extensions of human biology that help us navigate our environment.
The idea of an extended phenotype comes from biology, where structures like spider webs are not part of the spider’s body but serve important functions. Similarly, cultural practices and artifacts are not physically part of humans but help us survive and thrive.
Archaeological evidence shows that early hominins developed cultural tools and behaviors that enhanced their survival. But survival is more than just securing food and reproducing; it also involves flourishing — a concept discussed by Aristotle and other pre-evolutionary philosophers.
Anthropologist Leslie White argued in the 1950s that culture responds to biological needs, but these needs extend beyond the material to include spiritual and emotional dimensions. Life is challenging, and humans require encouragement, hope, and recreation to flourish.
Culture fulfills these broader needs. For example, music is a cultural practice that can be performed simply and resourcefully, yet it significantly enhances well-being. Such cultural solutions efficiently address human needs and contribute to overall flourishing.
Studying culture through an evolutionary framework helps us understand which cultural practices best meet human needs. It reveals that culture is not static or arbitrary but evolves in response to environmental pressures and human well-being.
Early theories of cultural evolution, known as cultural evolutionism, proposed a linear progression from simple tribes to complex civilizations, often implying an inevitable increase in political hierarchy with cultural complexity.
Recent scholarship challenges this view. For instance, David Graeber and David Wengrow, in their book The Dawn of Everything, argue that cultural evolution is not a predetermined march toward complexity or hierarchy. Instead, cultures exhibit a wide range of organizational forms and social structures.
Much like biological evolution, cultural evolution does not follow a single path. There is significant diversity in how cultures develop, influenced by environmental factors and human needs. This diversity reflects a feedback loop where culture adapts to meet the changing needs of its people.
Evolutionary thinking provides a nuanced understanding of culture as a dynamic, adaptive system that serves human survival and flourishing. It moves beyond simplistic analogies and outdated linear models to appreciate the complexity and diversity of cultural evolution. Recognizing culture as an extended phenotype that addresses both material and spiritual needs enriches our understanding of human social behavior and the role culture plays in our lives.
