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, goats, 1869 1872 | goats 1859 1860 1861 1866 |
in Europe alone, and several even within Great Britain. One author believes that there formerly existed in Great Britain
eleven wild species of sheep peculiar to it! When we bear in mind that Britain has now hardly
one peculiar mammal, and France but few distinct from those of
Germany, Germany, 1866 1869 1872 | Germany 1859 1860 1861 |
and conversely, and
so with Hungary, Spain, &c., but that each of these kingdoms possesses several peculiar breeds of cattle, sheep, &c., we must admit that many domestic breeds have
originated in Europe; for whence
