Q: Why Do We Wear Pants? A: Horses

Intro:

Whence came pants? I’m wearing pants right now. There’s a better than 50 percent chance that you, too, are wearing pants. And neither of us have probably asked ourselves a simple question: Why?

It turns out the answer is inexplicably bound up with the Roman Empire, the unification of China, gender studies, and the rather uncomfortable positioning of man atop horse, at least according to University of Connecticut evolutionary biologist Peter Turchin.
