Hey kids, as we all know, the evolution of species is an incredible process Driven by little more than the random chance that certain mutations may happen to provide a practical advantage in a creature's environment.

And as a result, there's a lot of things out there look super dumb once you strip back a few layers.

Here's the top 10 worst animal skeletons of all time.

So first and foremost, I'd like to set a little debate I've been seeing floating around the past few weeks. Yes.

Penguins do, in fact, have knees.

But in order to hide full-grown legs into one plump cylinder, you got to have a little skeletal trickery on your side.

You guys ever do wall sits in gym class or elsewhere?

One of the most torturous exercises out there.

I now feel even worse for penguins.

Because not only did they have to deal with living in a frigid black-and-white hellscape, the most hostile environment known to man second only to the vacuum of space, All the while constantly pursued by ravenous bloodthirsty sea dogs.
