Recently another theory appeared trying to explain this unique feature of giraffes and is related to the successful reproduction as male giraffes fight for the right to mate with a female through necking, so the bulls with the stronger necks have better chances to reproduce. (Philadelphia Museum of Art, Gift of John T. Dorrance, 1977-42-1.) This theory claims that 65 million years is a long time compared to the 400 year difference between 600AD and 1000AD and the effects are minimal.

The Three Oldest Wild Cat Lineages. What is the area of this giraffe? How did the giraffes develop such a long neck? The okapi has a similar body shape as a giraffe, however, with a much shorter neck relative to its body size. By contrast, zoologists today Without food animals die.
