The process of evolution is driven by natural selection from "summary" of NCERT Exemplar Problems-Solutions BIOLOGY class 12th by Arihant Experts
Natural selection is a key concept in the process of evolution. It refers to the mechanism by which certain traits within a population are favored over others, leading to changes in the gene pool over time. The basic premise of natural selection is that individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to future generations. One of the main drivers of natural selection is the environment in which a population lives. Environmental factors such as climate, food availability, predators, and competition for resources can all influence which traits are beneficial for survival and reproduction. For example, in a cold climate, individuals with thicker fur may be more likely to survi...
