Why did endurance cycling evolve? Oh, right, like endurance running, it didn't. I'm a human and I can't run far - unless I decided to train myself in that and then I can. Just as I could train myself to break dance. Did break dancing evolve? The book that created this 'theory' about running is nothing but running 'propaganda'. A meme pushed into the world by exercise addicted people who wanted a post-hoc 'naturalization' for their lifestyle.
