Natural selection and evolution play key roles in shaping biodiversity by driving the adaptation of species to their environments over time. Through the process of natural selection, individuals with advantageous traits that enhance their survival and reproductive success are more likely to pass on these traits to future generations. This leads to the accumulation of beneficial genetic variations within a population, ultimately resulting in the formation of new species and the diversification of life forms. Overall, natural selection and evolution contribute to the rich array of species and genetic diversity observed in ecosystems around the world.
