Sonorid Phenotype - Face Features & Origin
The Sonorid phenotype is a north america human phenotype documented in historical anthropology literature. This page presents the Sonorid phenotype average face composite, its geographic distribution, physical characteristics, historical background, and academic references.
Average Face
The Sonorid phenotype average face is a composite synthesized from multiple individual photographs by historical anthropologists. It represents a statistical impression of recurring facial features, not a real person.

Geographic Distribution
The Sonorid phenotype is native to North America. The historical distribution below reflects approximate centers of prevalence documented roughly 1500 years ago; modern borders and population movements have since blurred these boundaries.
Approximate coordinates: 45.00°, -100.00° (latitude, longitude).
Physical Characteristics
Yellowish-reddish medium to dark brown skin, straight or wavy black hair. (Rather) tall, meso- sometimes macroskelic, ectomorph, sometimes endomorph. Mesocephalic, mildly hypsicranic. Mesorrhine, straight or slightly convex nose. Lower face is pointed oval. More gracile and elongated compared to other Margids. Eyes usually not slanted.
Historical Background
Margid subtype, native to the hot Sonora desert of South Arizona and California, as well as Northwestern Mexico. Probably arrived with one of the earlier migrations to America. Today typified by the Pima (O'odham) and the Seri. More mixed in Yuma, Papago, Tlapaneco, and many other people of the Southern US and Mexico. Probably played an important role in the extinct inhabitants of Baja California.
