How and why have giraffes evolved?

Answer 1

Giraffes have evolved to exploit a particular ecological niche, which is, that they graze on tree leaves, which few animals are tall enough to reach. Whenever you have a niche that is not being exploited, that creates an evolutionary opportunity. There are many different animals that graze on grass, for example, so there is competition to eat the grass before some other species eats it, but leaves that are high off the ground are grazed on by very few animals (not counting insects, which are another matter - in any confrontation between a giraffe and an insect, the giraffe has a clear advantage).
