Huxleyan evolution

Huxleyan evolution, named after biologist Thomas Henry Huxley, emphasizes the importance of natural selection acting on random genetic variation to drive biological change over time. It proposes that evolution occurs gradually through small, cumulative differences within populations, shaping species through the survival and reproduction of advantageous traits. This concept underscores the idea that evolution is a continuous, incremental process, rather than sudden or caused by external forces, emphasizing the adaptive nature of living organisms as they evolve in response to their environment.
