> Anecdotally, when I watch a baby learn to walk, it doesn't really seem like they are trying a zillion things and picking the one that works. It seems much more like their instincts are telling them to move a certain way, and once they grow strong enough, it succeeds and they are walking.
How much of that comes from seeing everyone around them walking?
It seems hard to argue that horses don't have a genetic component, but I don't think Occam's Razor applies as well for humans when it takes 1-2 years of observing the world in order to start walking unsteadily.
