Giraffe

Dear Dr. Unc:

Why do giraffe has so long neck and what is this with evolution for? Bernt Brölund, from Norway.

Dear Bernie!

In my early studies in evolution at the University of Nairobi I spent a lot of time with giraffes. We found out that if you separate the neck and head the giraffe looks more like a snake with a huge head. Long time ago, at some point, this huge snake decided to molest a horse-like creature, perhaps a donkey, or a zebra. But it took thousands of years of molesting until the giraffe was good to go. Evolution is so beautiful!
