Zusätzlich zu seinen Beobachtungen während der Reise mit der „Beagle“ beschäftigte sich Darwin intensiv mit Organismen, die in Gefangenschaft gezüchtet werden, z.B. Tauben. Solche Zucht zielt meist darauf ab, Merkmale hervorzubringen, die vom Züchter gewünscht werden. Man spricht in solchen Fällen von "künstlicher Selektion".
