TopicHeard in 2 episodes across 2 shows since Jul 2026
Natural selection is the differential survival and reproduction of individuals due to differences in their relative fitness and observable characteristics. It is a key mechanism of evolution that changes the heritable traits of a population over generations. Popularized by Charles Darwin, it contrasts with artificial selection, which is driven by intentional human breeding.

Environmental changes create selection pressure for populations to adapt genetically.
“if there has been a change in environment that a population has experienced, for example, people have shifted to agriculture or begun living close to domesticated animals, or moved to a new environment from a cold place to a warm place or a low place to a high place, then there's pressure on the population to adapt to these new stresses, these new needs.”
