By some he has been declared a de= scendant of the wolf, and b}' others of the fox or jackal, and points of resemblance, such as cranial development, period of gestation, peculiarity of the eyes or carriage of the tail, have been cited in support of each theory. Still other writers have claimed he is of a distinct breed, and have attempted to prove this by the assertion that, though he will breed with all of the above animals, the progeny of the cross are incapable of propagation inter se^ thus proving they are true hybrids, oi' descendants of distinct species, it being a well-established principle that hybrids are sterile if bred together. This theory has, liowever, been completely refuted by observation of the dogs of the Indian tribes, as it has been proved beyond question that these cohabit with the wolves, foxes and coyotes, and that the progeny of these unions are as fertile as any others. From this fact modern authorities have come to the conclusion tlnat the dog is a mongrel, descended from crosses between all the animals to which he bears resemblance, and raised to his present per- fection by selection and breeding for specific results. Animals in a state of nature vary but little if any trom the original types, because they are 321 Digitized by Microsoft®.
