March of the Penguins

Evolution is so economical.

Penguins warm their eggs between their legs! How awkward this is! They can't walk fast, they can easily drop the eggs, and the male penguins need to maintain that posture for 4 months of the year!

What if there is a predator around the icy corner?

No, there isn't. That's the point. Evolution is not about elegance but practicality. It works for the little tuxie birds. No natural predators around, so they can afford to look awkward and be clumsy.

However, if there is ever a designer, His better work is obviously something with a pouch, hopping high and far gracefully. Penguins are perhaps the early prototype and most likely never went on to beta testing.

But they are still cute, so it's not an entirely lousy design.
