Origin of Species Variorum

Comparison with 1872

flows in the veins of our .. domestic breeds. In regard to sheep and goats I can form no decided opinion. I should think, from facts communicated to me by Mr. Blyth, on the habits, voice, .. constitution, and structure of the humped Indian cattle, it is almost certain that they are descended from a different aboriginal stock from our European cattle; and some 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 the specific distinction between the humped and common cattle, may indeed be looked at as almost established by the recent 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 belong to the same species. ↑ 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, some breeds of which differ much from each other, the evidence is clear that they are all descended from the common wild duck and rabbit.

The doctrine of the origin of our several domestic races from several aboriginal stocks, has been carried to an absurd extreme by some authors. They believe that every race which breeds true, let the distinctive characters be ever so slight, has had its wild prototype. At this rate there must have existed at least a score of species of wild cattle, as many sheep, and several goats, in Europe alone, and several even within Great Britain. One author believes that there formerly existed ... eleven wild species of sheep peculiar to Great Britain! When we bear in mind that Britain has now not one peculiar mammal, and France but few distinct from those of Germany, and .. so with Hungary, Spain, &c., but that each of these kingdoms possesses several peculiar breeds of cattle, sheep, &c., we must

From facts communicated to me by Mr. Blyth, on the habits, voice, and constitution, &c., of the humped Indian cattle, it is probable that these descended from a different aboriginal stock from our European cattle; and several competent judges believe that these latter have had more than one wild parent. ↑ With respect to horses, from reasons which I cannot here give, I am with much doubt inclined to believe, in opposition to several authors, that all the races have descended from one wild stock. Mr. Blyth, whose opinion, from his large and varied stores of knowledge, I should value more than that of almost any one, thinks that all the breeds of poultry have proceeded from the common wild Indian fowl (Gallus bankiva). In regard to ducks and rabbits, the breeds of which differ considerably from each other in structure, the evidence preponderates in favour of their having all descended from the common wild duck and rabbit.
