Dear Darwin - Episode 2

Five leading scientists address letters to Charles Darwin, expressing their thoughts on his work and legacy. Sir Jonathan Miller takes issue with Darwin's thoughts on reproduction. Darwin had no conception of modern genetics, but by the very nature of his work was tempted to speculate on the mechanism of reproduction. Jonathan questions why in this, one of the most central problem of biology, Darwin deviated from his otherwise exacting empirical standards, and support a just-so story of reproduction that could not even explain why circumcision was not inherited.
