ELEPHANT«

NICHE AND HOME« OF THE AFRICAN

ELEPHANT

´ The elephant lives in the grassy savannahs

deep in the heart of Africa.

´

It·s niche, or place and purpose in theenvironment, is to defoliate areas by stripping

trees of bark and branches with it·s large tusks

and elongated trunk.



NICHE, CONTINUED

´ The elephant is an herbivore. It is not a

predator, and is not usually preyed upon

because of its sheer size.

´ It has a symbiotic relationship with the small

cattle egret, which eats insects stirred up by

the grazing of the elephant.



NICHE, CONTINUED

´When an elephant has a baby, it is a large

commitment. Females are pregnant for nearly

22 months. They usually have a baby every two

to four years.

´ Other females of the herd can care for young,

too. It·s not just the mother that has a role in

raising her calf.



EVOLUTION



EVOLUTION, CONTINUED

´ The elephant·s first ancestors lived about 40

million years ago, and were the size of pigs and

cows.

´ Most of what·s known about elephants today

comes from their teeth ² as well as the fossils

of their bones and skeletons.

´ Throughout all of the elephant·s evolution,

there are many characteristics that have

appeared. Such as«



EVOLUTION, CONTINUED

´ Elongated limbs

« For traveling longer distances, and for reaching into

trees to eat foliage.

´ Tusks instead of teeth

« For digging into earth for roots and for stripping

bark away from trees

´ Development of a longer trunk

« For sucking in liquid to get into its massive mouth

and head. Also to pick up/move things and to make

it easier to get food.



PERSONAL VIEWS

´ I think that evolution is a very appealing idea,

and it gives a lot of explanation as to how

things act the way they do today. It shows that

animals can adapt to changing things in their

environment and proves Darwin·s theory of

natural selection.

´ If you look at the graph a few slides back, the

older elephants branching off are the ones that

didn·t make natural selection. This again

proves Darwin·s theory.



PERSONAL VIEWS, CONTINUED

´ I believe in spiritual explanation of how we got

here, but I also think that evolution is a very

probable explanation also. It just helps to have

some means of explaining of how we got here,

and how the organisms around us got here as

well.
