The Two Species of Elephants
In the present daytime there exists two species of elephants. These two species present many relatives that start come before them and died pop. Several of these species are Paleomastodon, Deinotherlum, Gompotherium, Prlmelephas which Is a direct ancestor to the modern day elephant, Stegadon, American mastodon, and wooly mammoth. whole of these species are considered Proboscidea which are mammals that have tree trunks proboscidea encompasses the trunked mammals (J.D. Illiger). indoors the probosciedea family there consists the elpephantidea, which elephants would be considered. There are many dfferent types of elephants due to where the species was locate and the types of plants in which they ate. The earliest common ancestor of all elephants was the Paleomastodon which originated in Africa close to 36-35 million years ago. It was a small mammal that had a trunk and it evolved into the many different species of elephant.One of the first species that adapted from the Paleomas tadon was the Delnothenum which lived In Africa and had tusks that pointed downward which helped it scarpe of speak from a tree. It also had a small brain which scientist believe Is trusty for Its extinction ue to lack of intelligence compared to other species. Gomphotherium is another species ot elephant that lived in the Americas, Europe, Delgrosso 2 and Asla and originated about 13 million years ago. It lived in waterlogged lake areas and marshes.This species had long tusks and a short trunked which was adapted to help It dig through with(predicate) mud to find aquatic vegetation. Stegadon which was the largest of all the species of elephants grew to its size to due to abundance of food that it would find in the parts of asia in which it lived. Most of them died out hundreds of housands of years ago boot out for a subspecies that lives in Indonesia on an Island of flores. This subspecies was smaller than the other species since it was secluded on an island and did not have access to as much food.The American Mastadon was found in the Americas and was a fur covered species of elephant, to help protect it from the colder climates, that was hunted Into extinction by humans about 10,000 years ago. Primeelephas is a direct genus to the modern day elephant and originated in Africa about 23 million years ago. It evolved Into three tonic species the Wooly mammoth, African elephant, and Asian elephant. The wooly mammoth lived in or so places In the northern hemisphere and was covered In a finishing of fur due to the cold climates in which it lived.It lived through the last deoxyephedrine age and died out at the end of it due to hunting and the readily climate change. The two living species of elephant left are the African elephant or loxodante and the Asian elephant or elephas. These two species are very similar except that the Asian elephant has an arched back while the t Of2 KS OT tne ATrlcan elephant. Delgrosso 3 ATrlcan elepnants DacK Is relatlvely st ralg an tne long-dated tus All species of animals must adapt to survive. It is through these adaptations that ifferent species arise.
