Martin Sixsmith looks at how our DNA and the development of our brains inform who we are and how we think.

He re-examines the nature versus nurture debate and considers the claims of evolutionary psychology from Robert Sapolsky's work with baboons to the increasing interest in epigenetics.

He talks to geneticist Steve Jones of University College London and visits the Oxford Brain bank to interview neuropathologist Margaret Esiri about the structure of the brain.
