Comparative cranial anatomy of Homo sapiens and Canis lupus familiaris: morphological, functional, and educational perspectives with a glance to biodiversity

Abstract

Cranial morphology reflects a species’ evolutionary history, functional adaptations, and environmental interactions. This comparative anatomical study examines the key structural differences between the cranium of humans (Homo sapiens) and that of domestic dogs (Canis lupus familiaris). Through a multi-level analysis encompassing gross anatomy, comparative anatomy, and anthropological implications, we highlight how evolutionary divergence, bipedalism, olfactory function, diet, and domestication have shaped the skulls of these two species. The findings underline the relevance of interspecies cranial comparisons for understanding human evolution, craniofacial development, and the broader patterns of mammalian biodiversity.
