Dog breeds developed their distinct characteristics through rapid natural evolution 11,000 years ago, not through human manipulation. Scientific analysis of ancient skulls shows that dogs naturally diversified into hunting, guarding and herding roles without the use of selective breeding programs. This morphological transformation occurred organically as dogs adapted to different environments and served different functions in early human societies.
