Note 1675 — XXI THE RELATIVE IMPORTANCE OF TRADITION AND HEREDITY

Wild oxen were abundant in Europe in the time of Julius Caesar, and of them the Chillingham herd may be a remnant. Horses were abundant in Europe in Neolithic times. But it is probable that both oxen and horses were first domesticated in Asia. The ovine group was originally situated in the mountain region of Central Asia, though Ovis savigni, apparently allied to the Argoli, has been found fossil in the Forest Bed of Norfolk (Flower and Lydekker, loc. cit., pp. 355, 357, 367, and 382).
