Curator Nick Ashton discusses the earliest human occupation of Britain with Iszi Lawrence. Featuring snippets from Nick's sell-out Members' lecture in January, the fourth episode of Membercast examines the British Museum's 15-year-old research project that began after the discovery of a family of footprints in Happisburgh, Norfolk.

The British Museum Membercast is a monthly podcast made available to 'all studious and curious persons'. Comedian, podcaster and super-fan Iszi Lawrence (The Z List Dead List) presents snippets from exclusive Members' lectures at the Museum, artfully woven together with interviews and her own musings.
