What is the future for humanity in this technological age? Why are we all getting fatter and how do genetics influence our relationship with food? Leading geneticist Dr Giles Yeo and academic Vybarr Cregan-Reid will discuss what makes us human; where we came from, who we are today and how modern technology will change us beyond recognition. One of the biggest threats to humanity is the current obesity epidemic and the pseudo-science diet culture. They will explore the history of our food, our bodies, and the ways we are changing our shape and our DNA. Vybarr teaches at the University of Kent and Giles is based at the MRC Metabolic Diseases Unit and is a regular BBC science presenter.
