Leo Q. Wan: Why are human bodies asymmetrical? (2016x9)

:

Symmetry is everywhere in nature. And we usually associate it with beauty: a perfectly shaped leaf or a butterfly with intricate patterns mirrored on each wing. But it turns out that asymmetry is pretty important, too — and more common than you might think. Leo Q. Wan takes us into the human body to show how biological asymmetry can be quite beautiful.
