The Two Species of Elephants
In the present mean solar day there exists two species of elephants. These two species keep up many relatives that have come in the lead them and died let out. Several of these species are Paleomastodon, Dein oppositelum, Gompotherium, Prlmelephas which Is a sharpen root to the modern day elephant, Stegadon, American mastodon, and wooly mammoth. All of these species are considered genus Proboscidea which are mammals that have trunks order Proboscidea encompasses the trunked mammals (J.D. Illiger). Within the probosciedea family there consists the elpephantidea, which elephants would be considered. in that respect are many dfferent types of elephants due to where the species was situated and the types of plants in which they ate. The earliest common ancestor of all elephants was the Paleomastodon which originated in Africa most 36-35 trillion eld ago. It was a small mammal that had a trunk and it evolved into the many different species of elephant.One of the first speci es that adapted from the Paleomastadon was the Del nonhenum which lived In Africa and had tusks that pointed downward(prenominal) which helped it scarpe of bark from a tree. It also had a small brain which scientist believe Is answerable 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 old age ago. It lived in swampy lake areas and marshes.This species had long tusks and a short trunked which was adapted to help It guesswork by dint of mud to find aquatic vegetation. Stegadon which was the largest of all the species of elephants grew to its size to due to teemingness of food that it would find in the move of asia in which it lived. Most of them died out hundreds of housands of years ago except for a subspecies that lives in Indonesia on an Island of flores. This subspecies was small than the other species since it was s ecluded on an island and did not have access to as such(prenominal) food.The American Mastadon was found in the Americas and was a skin cover species of elephant, to help harbor it from the colder climates, that was hunted Into extinction by world about 10,000 years ago. Primeelephas is a send out genus to the modern day elephant and originated in Africa about 23 million years ago. It evolved Into iii new species the Wooly mammoth, African elephant, and Asian elephant. The wooly mammoth lived in most places In the northern hemisphere and was covered In a coat of fur due to the cold climates in which it lived.It lived through the last ice age and died out at the end of it due to catch and the quick climate change. The two keep 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 elepna nts DacK Is relatlvely stralg an tne longer tus All species of animals mustiness adapt to survive. It is through these adaptations that ifferent species arise.
