What is natural selection?
Answer: Natural selection is a key mechanism of evolution, proposed by Charles Darwin. It is the process where organisms better adapted to their environment tend to survive and produce more offspring. This leads to the perpetuation of advantageous traits in a population over generations. Natural selection acts on the phenotype of an organism, meaning the physical characteristics and behavior that result from its genetic makeup. Certain variations allow individuals in a population to be better suited to their environment, increasing their chances of survival and reproduction. Over time, these advantageous traits become more common in the population, while less favorable traits diminish. In essence, natural selection is the engine that drives the adaptation of species to their environments, shaping the diversity of life on Earth.
