Your Inner Fish (2014 - 2014)

Episode 2 traces our hair, skin, teeth, jaws and sense of hearing back to reptilian ancestors - from ferocious beasts that ruled the Earth, to a little shrew-like animal that lived 195 million years ago.

In the final episode, Neil tracks our hands, feet, colour vision, spine and upright gait to our primate and hominid progenitors, who also passed on perhaps the most important legacy of all - a path to the human brain.
