12 Reasons Why Dogs Are Man's Best Friend

According to some scientists, the evolution of wolves into dogs occurred gradually and progressed as the relationship between dogs and humans improved. Another theory suggests that it all started with wolves scavenging for human scraps. The more human parts these wolves got, the more comfortable they were around humans. This led to the general but gradual acceptance of wolves among humans, who then selectively bred them for certain traits of interest. All of these encouraged their domestication and integration into the human world.
