Zea mays

You are holding a grass. It is smaller than your thumb, and it has eight — maybe twelve — hard little seeds arranged in two rows along a brittle cob. You would not look at it twice. And yet this is the plant that will, over the next nine thousand years, reshape the skeleton of human civilisation more completely than iron, more completely than the wheel, more completely than any idea anyone has ever written down. Its name, eventually, will be Zea mays. Right now it is a weed your ancestors keep returning to, for reasons they could not explain. The strange thing — the thing no one planned — is that the plant needed you back. Maize cannot reproduce without a human hand to strip the husk and scatter the seeds. Left alone in a field, it dies. It gave up that ability, kernel by kernel, over thousands of years of cultivation, trading wildness for the guarantee that you would never stop growing it. You domesticated the plant. The plant domesticated you. By the time anyone noticed the arrangement, entire cities had been built around the harvest, entire peoples had reorganised their bodies and their calendars and their gods to serve a grass that could not survive the winter without them. The question worth sitting with is this: who was farming whom?
