In the present day there exists two species of elephants. These two species have many relatives that have come before them and died out. 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. All of these species are considered Proboscidea which are mammals that have trunks "proboscidea encompasses the trunked mammals" (J.
D. Illiger). Within 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 located and the types of plants in which they ate. The earliest common ancestor of all elephants was the Paleomastodon which originated in Africa about 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 Paleomastadon was the Delnothenum which lived In Africa and had tusks that pointed downward which helped it scarpe of bark from a tree. It also had a small brain which scientist believe Is responsible 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 swampy lake areas and marshes.

This species had long tusks and a short trunked which was adapted to help It dig through 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 except 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 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 hunting and the quick 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.
