Based on the diversity of today’s dog breeds, scientists believe that your dog was formed by crossing several associated species from your dog family. Included in this, Charles Darwin  and the ethologist of Austria, Konrad Lorenz, had been the initiators of the idea of evolution, who concluded that the ancestors of the domestic dog had been a wolf and a jackal. Today’s set up opinion, supported by the full total results of genetic analyzes, can be that the domestic dog developed from a small group of wolves, domesticated about 15,000 years back.
It is not known exactly how the domesticated doggy was held. It is possible that canines were the ones who made the initial step. Namely, if crazy dogs started to be small enough to be unsafe, to go to human they could collect waste, discarded bones and camps. Thus, people tolerated them because they were cleansing their surroundings probably. It’s possible that they have begun to fascinate, approach them, and domesticize them as guard canines and companions. It had been only when agriculture has been progressing that the herds could possibly be preserved. Or elsewhere: the canines implemented a smarter line in the hope of getting anything from prey.
The initial remains of a domestic doggie were discovered in Mesolithic sites in different places. It appears that the initial European breed was quite small and would generally be best compared to today’s small dog.
Many breeds originate from a small amount of animals, which leads to mating in kinship. The result is various hereditary (genetic) diseases common in some breeds, for example hip dysplasia (specifically in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, among others
