Attenborough on Darwin

I've been listening to quite a few broadcasts and comments recently from Sir David Attenborough on Charles Darwin. Attenborough is still, at 82, one of the most convincing presenters I've ever heard. There's a written account that captures quite a lot of it here. Lots of controversy about what Darwin did and didn't know and the reporting of it, as discussed by David Chapman but Attenborough himself I find truly inspirational.
