Evolution Theory Discussion


According to Poinar (2013), fossils of the mammoth have been found inparts of Siberia and Northern Alaska. Their presence proves thatindeed mammoths walked the face of the earth a few million years ago.The woolly mammoths occupied the permafrost and arctic regions of theUSA. Their most likely region of origin, like human beings, wasAfrica. The mammal became extinct several million years ago. However,fossils of the woolly mammoth have been found in melted ice. Due tothe many years since their extinction, their DNA has somehowdisintegrated because of high temperatures and microbial impurities.Poinar (2013) and other scientists have been able to put together thepieces of mammoth DNA. By 2013, they had been able to sequence theentire 7 billion base pairs of mammoth DNA. The speaker is of theidea that if we inserted the mammoth DNA in an un-nucleated egg andthen artificially inseminate the Asian elephant, we could clone themammoth.

According to Knapton (2015), the Asian elephant and the wooly mammothhave a 99% match in their total DNA.

The genomic sequence of species differs in proportion to the timespent apart. As species spend time apart, they continue to evolveinto different forms as a way of adapting to their new environments.A good example is that of the mammoth and the Asian elephant. Theyboth migrated from Africa but after a few million years, they showeda difference in their DNA.

The genomic sequencing of the wooly mammoth (Poinar) has increasedour understanding of the evolutionary relationship between them andthe elephants. The sequence has revealed a 99% match with the modernelephants.

The knowledge of the genomic sequence of modern species can be usefulin the de- extinction of some species. Using the genome of the almostextinct white rhino, we could make several clones of the species.
