Origin of Species Variorum

Comparison with 1872

at an enormously remote period; and we know that at the present day there is hardly a tribe so barbarous, as not to have domesticated at least the dog. ↑

The origin of most of our domestic animals will probably for ever remain vague. But I may here state, that looking to the domestic dogs of the whole world, I have, after a laborious collection of all known facts, come to the conclusion that several wild species of Canidæ have been tamed, and that their blood, more or less mingled, flows in the veins of our many domestic breeds. In regard to sheep and goats I can form no opinion. I should think, from facts communicated to me by Mr. Blyth, on the habits, voice, and constitution, &c., of the humped Indian cattle, that these had descended from a different aboriginal stock from our European cattle; and several competent judges believe that these latter have had two or three wild progenitors, — whether or not these deserve to be called species. This conclusion, as well as that of the specific distinction between the humped and common cattle, may indeed be looked upon as almost established by the .. admirable researches of Professor Rütimeyer. With respect to horses, from reasons which I cannot give here, I am doubtfully inclined to believe, in opposition to several authors, that all the races have descended from one wild stock. ↑ having kept nearly all the English kinds alive, having bred and crossed them, and examined their skeletons, I have come to a similar conclusion, — the grounds of which will be given in a future work. In regard to ducks and rabbits, the breeds of which differ considerably from each other in structure, I do not doubt that they all have descended from the common wild duck

Having kept nearly all the English breeds of the fowl alive, having bred and crossed them, and examined their skeletons, it appears to me almost certain that all are the descendants of the wild Indian fowl, Gallus bankiva; and this is the conclusion of Mr. Blyth, and of others who have studied this bird in India. In regard to ducks and rabbits, some breeds of which differ much from each other, the evidence is clear that they are all descended from the common wild duck
