Canidae

Definition and stakes

Phebe Westcott Humphreys,  A Natural History for Young People…

“ The many different kinds of Dogs that are spread over the entire surface of the globe, with the Wolves, Jackals and Foxes, and their numerous smaller relatives are all grouped under the family of Canidae, which is derived from the Latin word Canis, meaning a Dog. All the members of this family are digitigrade. Though they walk on their toes, like the members of the Felidae, or Cat family, their claws are neither sharp nor retractile like those of the Cat and they cannot serve either for attack or defence. ”

Portrait of Charles Darwin Charles Darwin,  The Variation of Animals and Plants under Domestication…

“ Although it is possible or even probable that domesticated dogs, introduced into any country and bred there for many generations, might acquire some of the characters proper to the aboriginal Canidae of the country, we can hardly thus account for introduced dogs having given rise to two breeds in the same country, resembling two of its aboriginal species, as in the above- given cases of Guiana and of North America. ”
