The list is missing what IMHO is the most important reason: it took a really, really long time to transform wild plants and animals into useful domesticated varieties.

Bringing home some grains of that wild wheat that grows just a tiny bit larger. Befriending a wolf that is a little less distrustful of you. Picking that apple with the slightly smaller seeds. And so on.

Without those, you really are better off remaining a hunter-gatherer. People became significantly shorter when they first adopted a sedentary lifestyle.
