The incredible human journey

Sinopse

Alice Roberts has been travelling the world in order to understand the challenges that early humans faced as they tried to settle continents. Part detective story, part travelogue, and drawing on the latest genetic and archaeological discoveries, Alice examines how our ancestors evolved physically in response to these challenges, finding out how our colour, shape, size, diet, disease resistance and even athletic ability have been shaped by the range of environments that our ancestors had to survive.
