The neck of the giraffe is a bit of an enigma. How has the species managed to survive having such a cumbersome piece of anatomy.
Giraffes have long necks with only seven bones to support that crane-like instrument. Humans and many other species have the same number of bones, but with one major difference - the vertebrae in giraffe's neck each tend to be five inches longer.
The neck of a giraffe reminds me of the plant eaters of historic times. It must be a distinct advantage, as well as disadvantage, to reaching food. They need a lot of roughage to sustain themselves. With that long neck, they can reach places other animals can't to help their sustain diet.
Now the question also might be, how did the giraffes necks manage to get so long? The simple answer to this might be, 'stretching' to get at all those leaves in trees or grass on the ground. Evolution has a way of weeding out the weak, and we are talking about a very large animal that smaller species might have trouble tackling and devouring.
One would have to go back millions and millions of years to see how genetics developed, mutated, etc. to bring forward this unique animal living in the wild today. Could there be a link to a giraffe and a dinosaur to explain their species? It might be a stretch, but maybe someday archaeologists will find clues to put this puzzle of a creature together.
