Charles Darwin designed the scientific theory of evolution through natural selection. Evolution by natural selection was a process that was properly demonstrated by the observations. The observations reflected that more offspring are produced than those that end up surviving (Darwin, C., & Wallace, A. 1958). One of the examples that Darwin used to demonstrate natural selection was the fossil layers. The fossil layers are formed in sedimentary rocks. The sedimentary rock is commonly formed in the depositing and pressing of sediments on top of each other. After a long time, the layers of sediments get deposited on top of every layer. The weight of the upper layers presses forming into rocks called sedimentary rocks. One critical thing that Darwin noticed was that fossils in the bottom layers are still different from the alive today. Therefore, he concluded that organisms have not been the same since the beginning of the earth and that they gradually changed to a more complex organism. It was, therefore, critical to note that as new species arise, others become extinct. Thus, we look
