What Darwin Didn't Know

Visit the programme page

In 1859, Darwin gave us a bold and brilliant idea - evolution by natural selection. But there was so much he did not - could not - know about the workings of evolution. Ever since, other scientists have held his ideas up to scrutiny, and tried to fill in the gaps in evolution theory.

Evolutionary biologist Armand Leroi charts 150 years of scientific endeavour and explores the fall, renaissance and ultimate triumph of Darwin's ideas.

First broadcast 26 January 2009 on BBC Four.
