Natural Selection
In Charles Darwin’s “Natural Selection,” Darwin discusses his opinions on the natural selection, which he defines as “preservation of favorable variations and the rejection of injurious variations,” of nature, humans, and animals. During this writing, Darwin never states that he thinks he is correct in his theories, but that they are merely opinions in which he thinks may or may not be going on in nature. Darwin breaks up his writing into three different components: Natural Selection, Sexual Selection, and Illustrations of the Action of Natural Selection.

The main example he uses is at the beginning of the section, discussing how something as minor as a climate change in a natural environment could affect the habits or population of a certain species. He claims that the influence of a single type of plant or animal species can completely modify an entire environment.
Darwin also compares the natural selection of man to the natural selection of nature. He discusses how man makes his natural selections based on physical appearance, whereas nature cares nothing for the appearance of something, and makes its decisions based on what it needs to tend to.
Darwin says that natural selection is working every hour of every day throughout the world, rejecting everything that is bad, and savoring everything that is good, and improving everything possible. He covers how he thinks that animals that are certain colors are meant to be that way to blend in with their environment, which has been proven as a fact now, and is what we refer to now as “camouflage.” He also brings up the point that all animals are a certain color for a certain reason, and that the extinction of any particular species would have a great affect on the environment.
