Crikey, Mate #3
Evolution of Dogs: Modern science tells us that the DNA makeup of wolves and dogs is almost entirely identical. That poodle sitting in your lap is the product of 14,000 years of natural selection and artificial selection. Some scientists think the natural selection involved wolf pups that were better at begging food from humans. Others argue that the rise of the human refuse dump helped wolves domesticate themselves as they stayed within proximity of humans to feast at their food wastes. Either way, it seems all that was selected for was that one trait - to ability to eat in proximity to people.
