Food is profoundly social: defines family traditions and creates the medium for social interactions. Holidays require feast foods. Courtships require dinners out. All gatherings are improved by snacks. The lecturer will use a historical model, starting seven million years ago with the hunter gatherer tribal units who evolved into omnivory, to describe the subsequent food revolutions that followed: the first uses of fire and cooking; the domestication of animals and then plants; the first civilizations; the exchanges from one place to another of foods; and lastly the industrial production of food. All of which are connected to social, technological and cultural developments.
