In line with the diversity associated with today’s pup breeds, scientists believe that the dog was formed by crossing many related species from the dog family. Among them, Charles Darwin  and the ethologist of Austria, Konrad Lorenz, were the initiators of the idea of evolution, who figured the ancestors of the domestic dog were a wolf and a jackal. Today’s established opinion, supported by the full total outcomes of genetic analyzes, is usually that the domestic canine developed from the small group of wolves, domesticated about 15,000 years ago.
It isn’t known exactly how the domesticated dog was held. It’s possible that dogs were the ones who made the initial step. Namely, if wild dogs started to be small enough to become unsafe, to visit human discarded bones, camps plus they could collect waste. Thus, people tolerated them since they were cleansing their surroundings probably. It is possible they have begun to fascinate, approach them, and then domesticize them as guard dogs and companions. It was only when agriculture was progressing that the herds could possibly be preserved. Or otherwise: the dogs implemented a smarter range in the wish of getting anything from prey.
The initial remains of a domestic dog were discovered in Mesolithic sites in different places. It seems that the earliest European breed of dog was quite small and would generally be best compared to today’s small pet.
Many breeds originate from a small amount of animals, which leads to mating in kinship. The effect is various hereditary (genetic) illnesses common in a few breeds, for instance hip dysplasia (specifically in German shepherds), epilepsy, ataxia, oculoskeletal dysplasia, among others
