My safari & the neck of the giraffe

We went on a little expedition this weekend to do some animal research. We were very fortunate, and not only managed not to get eaten by predators but actually made a discovery that will revolutionize the world of zoology: the length of the giraffe's neck is not, as we conventionally thought, a result of the process of natural selection and the advantage this long neck conferred upon giraffes foraging for high-handing leaves.

The culprit is something closer to sexual selection, although I'm tempted to coin this hitherto unobserved mechanism as 'kinky selection,' or something of the sort: it's great for sticking up other giraffes' butts! Just look at the pictures...

Since we wanted to accurately study these and other animals, we didn't want our presence to influence their natural behavior, so we had to figure out a way to get close to them without making ourselves too obvious (we also didn't want to get eaten), so we came up with the brilliant plan of going undercover and blending in... Can you tell where we are in the pictures? That's right... I didn't think so...

By the way, as some of the pictures suggest, tons of animals are obsessed with sex, huh? They like to lick and finger themselves... a lot!!!
