Natural selection is a key mechanism of evolution, where organisms better adapted to their environment tend to survive and reproduce more successfully than others. Over generations, this leads to the gradual accumulation of advantageous traits in a population, shaping the species to better fit its environment. This process drives the diversity of life on Earth, as species evolve new characteristics to survive in changing conditions. Ultimately, natural selection explains how species change over time and how new species can arise, while less adapted species may decline or become extinct
