Biological Evolution

Biological evolution is the process by which living organisms change over generations through variations in traits. These variations arise from genetic mutations and are influenced by environmental factors. When certain traits help an organism survive and reproduce, they are more likely to be passed on to future generations. Over long periods, this can lead to the emergence of new species. Natural selection, where the fittest individuals thrive, is a key mechanism of evolution. Overall, evolution explains the diversity of life on Earth and how species adapt to their environments over time.
