Host Sam Harris finally gets to geek out on one of his obsessions - human pre-history and archeology. His guest is James Dilley, an expert in ancient technology and an experimental archeologist specialising in European ancient history from the Palaeolithic, Neolithic and the Bronze age.

In this episode, Sam and James discuss some of his most recent work for his PhD which focuses on the importance of quality shafts [for spear hunting that is], how the 'Paleo diet' would actually work, some incredible new finds and how each one changes much about previous ideas and how this can be a bit of a pain in the arse.....Plus A WORLD EXCLUSIVE!!!! Sam gives an indication of the annual fundraising activity he'll be doing this year.....and this time it's probably going too far.
