Seeing and doing : / preservation.

The first item on the programme is about dance and movement coordination. What makes some of us better at dance than others? Quentin Cooper talks to neuroscientists about how the brain 'mirrors' movement when we're watching someone else - this mirroring process can be applied to pain as well as motion. The second item is about the human desire to preserve things from the past, in particular our attempts to reconstruct the past from fossil records.
