I may add that as some organisms breed freely under the most unnatural conditions-for instance, rabbits and ferrets kept in hutches-showing that their reproductive organs are not easily affected; so will some animals and plants withstand domestication or cultivation, and vary very slightly-perhaps hardly more than in a state of nature.
Hau ere gehi dezaket, hots, organismo batzuk-kaioletan edukiriko untxiak eta hudoak, adibidez-baldintza desnaturalenetan mugapenik gabe umatzen diren moduan, honek ugal-organoak ez direla hain aise eraldatuak gertatzen erakusten digularik, halaxe animalia eta landare batzuek etxekotzeari edo lanketari eutsi eta oso gutxi aldatuko direla, agian natur egoeran baino ezer gutxi gehiagorik.
