McSweeney's does a take on how Chucky Darwin really got on board the Beagle . It's true- his Dad didn't want him to go. That voyage almost didn't happen.
Myself I tend to be a bit Platonic (actually, Romantic) about scientific insight. The order in the world exists independently of perception by individual personalities. Thus I think it's a mistake to hang too much of the theory of descent by natural selection on Darwin. Still, that guy knew how to write an argument. I have a copy of Origin and I still page through it.
