| The problem of the origin of domestic animals and plants, and the means by which they were produced along human history, were of deep interest to Charles Darwin who considered domestic breeding one grand experiment in evolution. In frst place, he elaborated an analogy between artifcial selection, by which breeders obtained desired characters in domestic species, and natural selection, the powerful force driving evolution in nature. At the same time, Darwin distinguished two processes within artifcial selection: methodical and unconscious selection. He attached great importance to the latter since it could produce gradual unexpected changes in association with those characters that were consciously selected for. Although the analogy natural/artifcial... |

| Phylogeographic studies are currently used to infer historical demographic processes such as gene fow, determination of effective population sizes, colonisation dynamics, and population botlenecks, as well as for the determination of species boundaries and the identification of possible conservation units. We present a review of the main contributions of this approach, and its applications and implications for canid conservation. Studies performed in canids have shown that the number of named subspecies is often larger than that of phylogeographic units. In recent times, the fragmentation of habitats has increased and one of the major concerns of conservation biologists is the occurrence of inbreeding. Large-sized canids have demonstrated to have enough... |
