Elephant Tusks Evolved From Teeth = Giving The Species An Evolutionary Advantage.
Ivory is an Elephant hard, white material from the Tusks – Elephant & Teeth of animals, that can be used in art or manufacturing. The chemical structure of the Teeth & Tusks of mammals is the same, regardless of the species of origin. The trade in certain Teeth & Tusks other than Elephant is well established and widespread; therefore, “Ivory” can correctly be used to describe any mammalian Teeth or Tusks of commercial interest which are large enough to be carved. Elephant Ivory is the most important source, but Ivory from hippopotamus, sperm whale, killer whale & warthog are used as well. Elk also have two Ivory Teeth, which are believed to be the remnants of Tusks from their Ancestors.
