If there exist savages so barbarous as never to think of the inherited character of the offspring of their domestic animals, yet any one animal particularly useful to them, for any special purpose, would be carefully preserved during famines and other accidents, to which savages are so liable, and such choice animals would thus generally leave more offspring than the inferior ones; so that in this case there would be a kind of unconscious selection going on.
Beren etxe-animalien ondorengoak herentziak izaeran markatzen dituela inoiz pentsatu ez izaterainoko basati barbaroak izanik ere, zerbaitaterako baliagarri zaien edozein animalia arretaz salbatu beharko lukete gosealdian edo basatiek hain maiz jasan behar izaten dituzten bestelako ezbeharretan, eta era horretan animalia hautetsiok beheragoko mailakoak baino ondorengo gehiago utziko lituzkete; eta kasu honetan mota bateko hautespen inkontzientea gertatuko litzateke.
