In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance.
Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. This leads to the evolution of species over time, as advantageous traits become more common in a population. This is evidenced through observations of finches on the Galapagos Islands, where variations in beak shape allowed for different feeding habits and eventually led to the formation of multiple distinct species. The four parts of natural selection include variation within a population, competition for resources, survival of the fittest, and passing on advantageous traits to offspring. These processes contribute to the gradual changes in species that we see over time.
