1. From Landscape to Seascape

Professor Sanjeev Gupta of Imperial College London goes back 450,000 years, to a time when our ancestors could walk across a rock ridge from the chalk cliffs near Calais to our own at Dover.

At the British Museum, Nick Ashton, Curator of Palaeolithic and Mesolithic collections, shows him artefacts that provide evidence they did.

The Channel is a reflection on the stretch of water that both separates us from and connects us to Europe.

This series examines how this waterway has affected our British identity through time, and continues to do so.

Music composed by Phil Channell.

Producer: Marya Burgess.

First broadcast on BBC Radio 4 in March 2018.
