Evolution can be defined as a gradual process in which a species changes into a different and more complex form. This happens over several generations. Evolution also proves that all species are related through genetic variation. (yourgenome.org, n.e). Charles Darwin (1809-1882) was an English Naturalist, famous for creating the theory of ‘evolution’. He also created a theory that species survive through a process called “natural selection”. The species that successfully adapted to meet the requirements of their natural habitat lived on for generations while species that failed to evolve and breed died off (Bio, 2016). Charles Darwin has proof to back up that his theory of evolution, an …show more content…
Fossils prove Charles Darwin’s theory of evolution. This due to the fact that evolution is a ‘gradual process in which a species changes into a different and more complex form’ as can be see each bone gradually changes into a more complex and different form. In the first bone (Hyracotherium) the bone has appendages on its foot, this was in the Paleocene–Eocene Thermal Maximum period. This period was really wet with mud etc. and the temperature was rising so the ground would have hardened up. So their toe features would help them not sink into mud. There then is a huge jump in time period (Mesohippus) the horse lost a phalange, this was the Middle Eocene Climatic Optimum period and once again the climate was rising so they ground hardened and the horses adapted to that. Eventually the horse’s leg got longer making bigger strides when running, their feet turned into a hoof making them also run faster from prey. Therefore, due to figure one showing gradual change, fossils prove Darwin’s theory …show more content…
The more closely species are related the more closely their DNA sequences will overlap. Even very distantly related species will have some degree of DNA sequence overlap. Similar DNA species are closely related. DNA Sequencing is used in genetics lab to find missing pieces in DNA strands. An example of how DNA sequencing is how these animals are all related.

Figure two proves DNA sequencing proves Darwin’s theory of Natural Selection. ‘species that successfully adapted to meet the requirements of their natural habitat lived on for generations while species that failed to evolve and breed died off’. In this picture you can see that at the first animal has evolved into another animal, so it has died off and then with the theory of evolution it has evolved into something different, and the chain keeps going on until it has evolved into a whale. So with DNA sequencing it is clear that these animals are still related because their DNA overlaps.
To conclude Darwin’s theory of Natural Selection is reliable and is supported. Evidence that support his theory is DNA Sequencing with animals being all related through genetic variation and Fossils showing animals evolve for better so they do not die
