Natural Selection Vs. Species Variation

Evolution is the change of something over time. The evolution of our earth, and it species has been a very debated topic over time. There is a lot of evidence that supports evolution and you have found a lot of great evidence that proved this theory to be true. The proposal that species variation locally, globally and over time was your idea, and is agreed with widely today. Natural selection is one of your other theories that is known all over the world today. Both natural selection and species variation have helped develop the theory of evolution and have strong evidence supporting them.
Species variation has three parts to it, one being species change over time. Charles Darwin discovered this idea while on his voyage. While looking at fossils and old skeletons from past animals Darwin noticed similarities between bone structure now and the bone structure from the fossil. Some of his findings include that many animals today did come from a common ancestor. Darwin found that the bone structure in both the human arm, and the fin of a whale are the same or very similar, so he concluded that they came from a common ancestor. We also have found fossils of animals very similar to the ones we
Charles Darwin was the man who thought of this idea of natural selection. I believe that natural selection is a process of evolution that helps many species survive and thrive in their environments. Natural selection helps species adapt to new or changing environments to help them survive better. An example of natural selection in the real world would be the pollution of a lake causing it to become darker then slowly over time as the fish reproduce there would be no light fish, all fish would be dark. Natural selection is basically survival of the fittest. Natural selection has allowed a variation of species to thrive in different
