Evolution is the process by which populations of organisms change over generations. This change is driven by several mechanisms, primarily natural selection. Here's a breakdown: 1. Variation: Within any population, individuals have slight differences in their traits. These variations arise from random genetic mutations. 2. Inheritance: These traits are passed down from parents to offspring through genes. 3. Selection: In any given environment, some traits are more advantageous than others for survival and reproduction. Individuals with these advantageous traits are more likely to survive and pass them on. This is natural selection. 4. Time: Over long periods, these advantageous traits become more common in the population, leading to significant changes in the species. This gradual change is evolution. A classic example is the peppered moth in England. Before the Industrial Revolution, most peppered moths were light-colored, blending in with lichen-covered trees. Darker moths were easily spotted by birds. During the Industrial Revolution, pollution killed the lichen and darkened the trees with soot. Now, the dark moths were better camouflaged, and they became more common. What's next?
