Evolutionary Mechanisms

This article talks about Evolutionary mechanisms and how the same species can come to look like a completely different species. "Natural Selection" is a big part in evolutionary mechanisms. Natural selection is basically "survival of the fittest," meaning that depending on the environment, color, size etc; only certain species will survive. Coming off of that, explaining evolutionary mechanisms is basically the genes a species has and how much they vary. Depending on what genes they inherit, that will determine physical looks. According to the article "Evolutionary mechanisms" from Gale Resources, "With directional selection an extreme phenotype is favored (e.g., for height or length of neck in giraffe)."
