  One big advantage is that we can run while breathing out of sync with our steps. Four legged running pretty much requires each inhale and exhale to sync with the compression and expansion of the torso with each stride. Humans, on the other hand, can run full speed while taking multiple steps per breath, depending on terrain and fatigue, which gives more options for pacing.

    Interesting, that dynamic is in line with the ‘radiator’ theory of human brain evolution.

    From a more recent article:

    the shift to an aerobic, hunter-gatherer lifestyle in early Homo, including long-distance running, exerted selection pressures that favored both increased endurance and enhanced brain growth

  I saw it in a documentary but it was a good while ago so to be honest I can’t remember what the exact mechanism was or if it was just a contributing factor over longer distances. I just remember storing it away as little nugget that made sense when presented.

  It’s very late here and now you have me curious so I’ll probably have a dig around in the morning.
