Some quarters believe that the female survival rate without these genes is due to the high survival rate of female elephants without tusks. These elephants can survive equally, using their size ...
Tusks are thought to have adapted to the extra-oral environments, like dry or aquatic or arctic. [1] 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.

Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen ...
