LSE-based researchers have been involved in making a BBC documentary called The Family That Walks On All Fours, due to be broadcast on Friday 17 March (BBC Two, 9-10pm).
The documentary tells the story of a remarkable family in Turkey, five of whom, aged between 18 and 34, walk quadrupedally.
Professor Nicholas Humphrey, of LSE's Centre for Philosophy of Natural and Social Science (CPNSS), is one of the scientists who've made contact with the family.
He and Dr John Skoyles, a CPNSS research associate in residence, and a member of the CoMPLEX group at University College London, are among a number of scientists featured in the documentary who have a variety of views on why the family might walk this way.
Evolutionary psychologist, Professor Nicholas Humphrey said: 'This could be hugely important - a living example of how our ancestors walked before they became bipedal. As such it might teach us so much about our distant past.'
BBC Two's The Family That Walks On All Fours is on Friday 17 March at 9pm - see http://www.bbc.co.uk/pressoffice/pressreleases/stories/2006/03_march/07/fours.shtml
