The Meanings of Evolution

Evolution is the process by which populations of organisms change over time through genetic variations. These changes can improve an organism's ability to survive and reproduce in its environment. Over many generations, beneficial traits become more common, leading to the development of new species. Evolution is driven by mechanisms like natural selection, mutation, and genetic drift. It explains the diversity of life on Earth and how species adapt to their surroundings. Essentially, evolution is nature’s way of shaping living things gradually, enabling them to better fit their ecological niches over long periods.
