How Evolution Innovates by Exploring Genotype Space | Andreas Wagner
Andreas Wagner is a biologist studying the mechanisms of evolution.
Evolution not only generates novel innovations but does so repeatedly. For example, the eye has evolved independently around 50 times across different species throughout evolutionary history. How does evolution consistently discover such innovations?
Andreas Wagner's research group explores the underlying structure of genotype spaces to map out the possible innovations that can arise. By examining how evolution navigates this space through genetic mutations, they aim to understand how valuable traits emerge.
In this podcast, expect to learn whether evolution operates solely through DNA, how evolution is being studied through lab experiments, the mathematical structure of genotype spaces that evolution explores, whether DNA is the only medium for evolutionary processes, and more...
