Evolution is not Necessarily Progressive
Evolution is not necessarily Progressive: Evolution should not be equated with progress. There is no real progress in the concept of evolution. It is simply the generation of diversity by natural selection and its shaping by environmental selection. The concept of evolution is not that the animals and the plants, we see around us have evolved from each other or that after the evolution of one species the other got eliminated. It will all depend on the environment. It is just that natural selection and genetic drift have together led to the formation of a population that cannot reproduce with the original one. In fact, some species share similar features as they evolved from a common ancestor. Take for example, the case of human beings and chimpanzees. It is not true that human beings have evolved from chimpanzees. Rather, humans and chimpanzees share more similarities than the other types of apes, which mean that they probably share a more recent ancestor or common ancestor than the others.
