Web15 de ene. de 2024 · Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment. Thus, natural selection is constantly influencing the evolution of species. WebHeritability is a measure of how well differences in people’s genes account for differences in their traits.
