Well there's also the fact that something like "agriculture" isn't invented by one person at one time. It's a long slow process of artificial selection to get food crops out of wild plants. The domestication of plants probably was largely pushed by artificial selection via female gatherers, to the same extent that animal husbandry was probably pushed by artificial selection via male hunters. And not consciously. I doubt any cavewoman was picking through wild grasses thinking "someday these will be edible enough I can start making designer cupcakes and get fat!"
