Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive. This process is known as natural selection, which explains how Charles Darwin’s theory of evolution can occur. Natural selection is an important component of evolution. It occurs when some members of a population are better fit for survival and proliferation than others in that population. The environment in which organisms live plays a large part in natural selection as well. Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds. Fortunately, the Viceroy population has increased significantly primarily due to mimicry [Viceroy
