Once common throughout Africa and Asia, elephants have declined significantly during the 20th century, largely due to the illegal ivory trade. Though some populations are now stable and growing, poaching, human-elephant conflict, and habitat destruction continue to threaten the species.
Elephants are the largest land mammals on earth and have distinctly massive bodies, large ears, and long trunks. They use their trunks to pick up objects, trumpet warnings, greet other elephants, or suck up water for drinking or bathing, among other uses. Both male and female African elephants grow tusks and each individual can either be left- or right-tusked, and the one they use more is usually smaller because of wear and tear. Elephant tusks serve many purposes. These extended teeth can be used to protect the elephant's trunk, lift and move objects, gather food, and strip bark from trees. They can also be used for defense. During times of drought, elephants even use their tusks to dig holes to find water underground.
The African elephant is the largest of all elephant species and weighs up to eight tons. Two genetically different African subspecies exist: the savanna and the forest elephant, with a number of characteristics that differentiate them both.
Asian elephants differ in several ways from their African relatives, with more than 10 distinct physical differences between them. For example, Asian elephants are smaller than their African cousins, and their ears are smaller compared to the large fan-shaped ears of the African species. Only some male Asian elephants have tusks, while both male and female African elephants grow tusks.
Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with pigs, hippos, and walruses, or, in the case of elephants, elongated incisors. In most tusked species both the males and the females have tusks although the males' are larger. Most mammals with tusks have a pair of them growing out from either side of the mouth. Tusks are generally curved and have a smooth, continuous surface. The narwhal's straight single helical tusk, which grows out from the center of the mouth and is present only in the male, is an exception to the typical features of tusks described above. Continuous growth of tusks is enabled by formative tissues in the apical openings of the roots of the teeth.

Answer:
Elephant tusks evolved from teeth, giving the species an evolutionary advantage. They serve a variety of purposes: digging, lifting objects, gathering food, stripping bark from trees to eat, and defense. The tusks also protect the trunk—another valuable tool for drinking, breathing, and eating, among other uses.
