The Variation of Animals and Plants under Domestication — Volume 1. Darwin Charles

in the frequent presence of "nilgau-like markings on their feet," and "in the one being born with teeth protruding through the jaws, and the other not so." They have different habits, and their voice is entirely different. The humped cattle in India "seldom seek shade, and never go into the water and there stand knee-deep, like the cattle of Europe." They have run wild in parts of Oude and Rohilcund, and can maintain themselves in a region infested by tigers. They have given rise to many races differing greatly in size, in the presence of one or two humps, in length of horns, and other respects. Mr. Blyth sums up emphatically that the humped and humpless cattle must be considered as distinct species. When we consider the number of points in external structure and habits, independently of important osteological differences, in which they differ from each other; and that many of these points are not likely to have been affected by domestication, there can hardly be a doubt, notwithstanding the adverse opinion of some naturalists, that the humped and non-humped cattle must be ranked as specifically distinct.

      The European breeds of humpless cattle are numerous. Professor Low enumerates 19 British breeds, only a few of which are identical with those on the Continent. Even the small Channel islands of Guernsey, Jersey, and Alderney possess their own sub-breeds (3/34. Mr. H.E. Marquand in 'The Times' June 23, 1856.); and these again differ from the cattle of the other British islands, such as Anglesea, and the western isles of Scotland. Desmarest, who paid attention to the subject, describes 15 French races, excluding sub-varieties and those imported from other countries. In other parts of Europe there are several distinct races, such as the pale-coloured Hungarian cattle, with their light and free step, and enormous horns sometimes measuring above five feet from tip to tip (3/35. Vasey 'Delineations of the Ox-Tribe' page 124. Brace 'Hungary' 1851 page 94. The Hungarian cattle descend according to Rutimeyer 'Zahmen Europ. Rindes' 1866 s. 13 from Bos primigenius.): the Podolian cattle also are remarkable from the height of their fore-quarters. In the most recent work on Cattle (3/36. Moll and Gayot 'La Connaissance Gen. du Boeuf' Paris 1860. Fig. 82 is that of the Podolian breed.), engravings are given of fifty-five European breeds; it is, however, probable that several of these differ very little from each other, or are merely synonyms. It must not be supposed that numerous breeds of cattle exist only in long-civilised countries, for we shall presently see that several kinds are kept by the savages of Southern Africa.

      [With respect to the parentage of the several European breeds, we already know much from Nilsson's Memoir (3/37. A translation appeared in three parts in the 'Annals and Mag. of Nat. Hist.' 2nd series volume 4 1849.), and more especially from Rutimeyer's works and those of Boyd Dawkins. Two or three species or forms of Bos, closely allied to still living domestic races, have been found in the more recent tertiary deposits or amongst prehistoric remains in Europe. Following Rutimeyer, we have: Bos primigenius.

      This magnificent, well known species was domesticated in Switzerland during the Neolithic period; even at this early period it varied a little, having apparently been crossed with other races. Some of the larger races on the Continent, as the Friesland, etc., and the Pembroke race in England, closely resemble in essential structure B. primigenius, and no doubt are its descendants. This is likewise the opinion of Nilsson. Bos primigenius existed as a wild animal in Caesar's time, and is now semi-wild, though much degenerated in size, in the park of Chillingham; for I am informed by Professor Rutimeyer, to whom Lord Tankerville sent a skull, that the Chillingham cattle are less altered from the true primigenius type than any other known breed. (3/38. See also Rutimeyer 'Beitrage pal. Gesch. der Wiederkauer' Basel 1865 s. 54.)

      Bos trochoceros.

      This form is not included in the three species above mentioned, for it is now considered by Rutimeyer to be the female of an early domesticated form of B. primigenius, and as the progenitor of his frontosus race. I may add that specific names have been given to four other fossil oxen, now believed to be identical with B. primigenius. (3/39. Pictet 'Palaeontologie' tome 1 page 365 2nd edition. With respect to B. trochoceros see Rutimeyer 'Zahmen Europ. Rindes' 1866 s. 26.)

      Bos longifrons (or brachyceros) of Owen.

      This very distinct species was of small size, and had a short body with fine legs. According to Boyd Dawkins (3/40. W. Boyd Dawkins on the British Fossil Oxen 'Journal of the Geolog. Soc.' August 1867 page 182. Also 'Proc. Phil. Soc. of Manchester' November 14, 1871 and 'Cave Hunting' 1875 page 27, 138.) it was introduced as a domesticated animal into Britain at a very early period, and supplied food to the Roman legionaries. (3/41. 'British Pleistocene Mammalia' by W.B. Dawkins and W.A. Sandford 1866 page 15.) Some remains have been found in Ireland in certain crannoges, of which the dates are believed to be from 843-933 A.D. (3/42. W.R. Wilde 'An Essay on the Animal Remains, etc. Royal Irish Academy' 1860 page 29. Also 'Proc. of R. Irish Academy' 1858 page 48.) It was also the commonest form in a domesticated condition in Switzerland during the earliest part of the Neolithic period. Professor Owen (3/43. 'Lecture: Royal Institution of G. Britain' May 2, 1856 page 4. 'British Fossil Mammals' page 513.) thinks it probable that the Welsh and Highland cattle are descended from this form; as likewise is the case, according to Rutimeyer, with some of the existing Swiss breeds. These latter are of different shades of colour from light- grey to blackish-brown, with a lighter stripe along the spine, but they have no pure white marks. The cattle of North Wales and the Highlands, on the other hand, are generally black or dark-coloured.

      Bos frontosus of Nilsson.

      This species is allied to B. longifrons, and, according to the high authority of Mr. Boyd Dawkins, is identical with it, but in the opinion of some judges is distinct. Both co-existed in Scania during the same late geological period (3/44. Nilsson in 'Annals and Mag. of Nat. Hist.' 1849 volume 4 page 354.), and both have been found in the Irish crannoges. (3/45. See W.R. Wilde ut supra; and Mr. Blyth in 'Proc. Irish Academy' March 5, 1864.) Nilsson believes that his B. frontosus may be the parent of the mountain cattle of Norway, which have a high protuberance on the skull between the base of the horns. As Professor Owen and others believe that the Scotch Highland cattle are descended from his B. longifrons, it is worth notice that a capable judge (3/46. Laing 'Tour in Norway' page 110.) has remarked that he saw no cattle in Norway like the Highland breed, but that they more nearly resembled the Devonshire breed.]

      On the whole we may conclude, more especially from the researches of Boyd Dawkins, that European cattle are descended from two species; and there is no improbability in this fact, for the genus Bos readily yields to domestication. Besides these two species and the zebu, the yak, the gayal, and the arni (3/47. Isid. Geoffroy Saint-Hilaire 'Hist. Nat. Gen.' tome 3, 96.) (not to mention the buffalo or genus Bubalus) have been domesticated; making altogether six species of Bos. The zebu and the two European species are now extinct in a wild state. Although certain races of cattle were domesticated at a very ancient period in Europe, it does not follow that they were first domesticated here. Those who place much reliance on philology argue that they were imported from the East. (3/48. Idem tome 3 pages 82, 91.) It is probable that they originally inhabited a temperate or cold climate, but not a land long covered with snow; for our cattle, as we have seen in the chapter on Horses, have not the instinct of scraping away the snow to get at the herbage beneath. No one could behold the magnificent wild bulls on the bleak Falkland Islands in the southern hemisphere, and doubt about the climate being admirably suited to them. Azara has remarked that in the temperate regions of La Plata the cows conceive when two years old, whilst in the much hotter country of Paraguay they do not conceive till three years old; "from which fact," as he adds, "one may conclude that cattle do not succeed so well in warm countries." (3/49. 'Quadrupedes du Paraguay' tome 2 page 360.)

      Bos primigenius and longifrons have been ranked by nearly all palaeontologists as distinct species; and it would not be reasonable to take a different view simply because their domesticated descendants now intercross with the utmost freedom. All the European breeds have so often been crossed both intentionally and unintentionally, that, if any sterility had ensued from such unions, it would certainly have been detected. As zebus inhabit a distant and much hotter region, and as they differ in so many characters from our European cattle, I have taken pains to ascertain whether the two forms are fertile when crossed. The late Lord Powis imported some zebus and crossed them with common cattle in Shropshire; and I was assured by his steward that the cross-bred animals were perfectly fertile with both parent-stocks. Mr. Blyth informs me that in India hybrids, with various proportions of either blood, are quite fertile; and
