The giraffe can run up to 35 miles per hour for short distances and spends most of its time standing up, including to sleep and to give birth. During the 19th and 20th centuries, overhunting, habitat destruction, and rinderpest epidemics introduced by European livestock reduced giraffes to less than half their former range. Today giraffes are numerous in East African countries and also in certain reserves of Southern Africa, where they have Giraffe (Giraffa camelopardalis), with their long neck and legs, are unique amongst mammals. How these features evolved is a matter of conjecture. The two leading ideas are the high browse and the sexual-selection hypotheses.

Evolutionary scientists believe these differences, the genetic underpinning of what makes a giraffe a giraffe, are the result of random mutations accumulated over millions of years. They believe the giraffe evolved from a common ancestor shared with cattle by way of these mutations.
