Dog Breed Evolution Chart: From Wolf Ancestor to Modern Breeds #1959908 (License: Personal Use)

This circular cladogram visualizes the evolutionary relationship between the gray wolf (Canis lupus) and modern domestic dog breeds, organized by functional categories (e.g., herding, scent hounds, toy dogs) and geographic origins (Europe, Asia, Middle East). Branch thickness and color gradients indicate relative genetic divergence and historical breed development timelines, with ancient breeds like Basenji and Afghan Hound positioned near the root. The chart highlights how human-driven selection over millennia shaped morphological and behavioral diversity.

Used in educational biology or veterinary science articles, pet breed guides, or evolutionary anthropology resources; targets users seeking to understand canine phylogeny, breed origins, or domestication history.
