Repeat: BBC2 (not Northern Ireland) Tue 5 Feb 11:20pm2/5. Professor Brian Cox travels across America encountering a diverse range of creatures that reveal how the senses evolved. In Kentucky, he explains how microscopic single-celled organism the paramecium can orientate itself through touch alone, and that catfish build a picture of their murky river environment through the taste buds that cover their bodies. Investigating the eyes of octopuses, Brian finds a link between the ability to process sensory data and intelligence, which may be evidence that humans evolved large brains in order to make sense of what they could see.
