This episode is dedicated to a very particular theme. With Alberto Angela we take a truly unusual journey around our kitchen: we explore objects that we all have at home, but that ultimately we know very little about. Things that upon closer inspection show us the main stages of the evolution and history of the human species, sometimes the result of very ancient technologies, other times born from modern science. No place in our homes reveals something about our human being more than the kitchen. This anthropological expedition takes us to every corner of the world, and to every period of history. Human beings' need to eat has led to an incredible circulation of animal and plant species across the globe. Exchanges, commerce and migrations of the different populations were accompanied by the spread of their foods. Following the traces of these ancient food imports is very difficult. Except in a few cases: those of foods from more recently discovered lands.
