Natural selection Definition & Processes Britannica

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not. WebNatural selection acts on populations through a specific trait. Which statement must be true about that trait? answer choices The trait is resistant to mutations. The trait is passed on genetically to the next generation. Most forms of the trait have the same impact on survival. The trait is the same for all organisms.
