Are modern women somehow fighting against nature in the way they breastfeed? Have the "natural skills" been lost in the modern lifestyle? No to the first, maybe to the second. Evolution A/B testing only works at the level where something influences the ability of successive generations to survive. It also selects for whatever barely works. As far as evolution is concerned, there is no difference between it being easy to do, and learnable. If all women end up learning (say, for other more experienced mothers), then there's nothing for evolution to select for. It's unfortunate for the woman who has trouble at first (like my wife, for instance) but it clearly isn't evolutionarily significant.
