👉 Evolution is a biological process by which species evolve over time, through a series of changes and adaptations. This process can take place in various forms, including genetic mutations, natural selection, and environmental factors. It involves the gradual change or improvement of an organism's traits, such as size, shape, color, or behavior, over generations. The evolution of life on Earth is a complex system that has been studied for centuries, with many scientists and researchers contributing to our understanding of how species evolve.
