A young Welshman, Alfred Russel Wallace from Usk in Monmouthshire, was responsible for the theory of evolution and not Charles Darwin according to a controversial documentary Darwin, y Cymro a'r Cynllwyn (Darwin, the Welshman and the Conspiracy).
The programme shows how Darwin lied and concealed the fact that it was letters from Wallace, a beetle collector, which formulated the ideas behind the theory.
Darwin, y Cymro a'r Cynllwyn is a detective story, which unravels one of the greatest injustices in the history of science. It's a programme which revolutionises our understanding of how Charles Darwin arrived at the ideas that underpinned his theory of evolution as presented in 'The Origin of Species'.
