3. We’re genetically programmed to run
Most scientists (including Harvard anthropologist Daniel Lieberman, who published an oft-quoted study in 2007) believe that our ancestors were daytime hunters and scavengers. In other words, those guys had to get to the animal faster than any other hunter, or else there would be no food for dinner. What’s the link between those old guys and you? Um, have you heard of Darwin?
4. We are curious
Just think, modern humans moved from Africa to Asia around 75,000 years ago. From there, to South Asia, 50,000 years ago, to Australia 46,000 years ago, and Europe 43,000 years ago. That’s some major wanderlust. We run because we are movers and we always want to see the next trail, the next vista, the next continent, and the next world. If we weren’t good at getting places, we’d have been stuck.
