Why evolution explains more than we think

Evolution is often misunderstood as a process limited to biology and genes. In this in-depth conversation, evolutionary ecologist Mark Vellend challenges that narrow view and presents a powerful idea: evolution is a universal principle that governs all complex systems.

In this episode of Reason with Science, we explore how evolution applies not only to living organisms, but also to languages, technologies, cultures, institutions, scientific theories, economics, and artificial intelligence. Drawing on his book Everything Evolves: Why Evolution Explains More Than We Think (From Proteins to Politics), Mark Vellend explains why evolutionary theory deserves recognition as a general science of change, alongside physics.

We discuss:-

•What makes a system evolutionary in the most fundamental sense

• Why Darwinism shaped — and narrowed — our understanding of evolution

• How languages evolve through everyday use and variation

• Why technologies advance through trial, error, and selection

• How cultural norms, ideas, and institutions evolve over time

• The role of randomness, contingency, and selection beyond biology

• Evolutionary thinking in AI, economics, and complex systems

• Tipping points, feedback loops, and irreversible change in ecosystems and societies

This episode is essential viewing for scientists, students, educators, philosophers, and anyone curious about how the world changes — from cells to civilizations.
