Regional Human Hair Characteristic Variates

The older terms “Mongoloid,” “Caucasoid,” and “Negroid” used to describe the major population groups of humankind are replaced in this atlas with the more modern terms East Asian, European, and African (meaning sub-Saharan African), respectively. These terms were adapted from Brace.
The populations of the Indian subcontinent are allied with the European populations in terms of anthropological kinship.However, the scalp hair of the Indian subcontinent populations is more closely allied with the hair type of the East Asian populations, as is the scalp hair of the native populations of North, Central, and South America. Although the native populations of the Americas are allied with the East Asians anthropologically, many of the populations of Mexico and the other countries of Central and South America are of mixed heritage, so the scalp hair of these populations may represent characteristics consistent with those of a mixed heritage.
Forensic anthropologists rely primarily on skeletal analysis for an accurate estimate of original geographic origins. The depth of skin pigmentation has considerable overlap between individuals of African, European, and East Asian geographical origin, as does hair form among individuals of European, African and East Asian populations. Hair color, form, and degree of curl, however, can provide an indication of the geographical ancestry of the individual from whom a questioned hair originated. Those indications of the geographical heritage of an individual who is the source of a questioned hair can be of considerable value in the forensic examination of human hair, particularly with regard to providing investigative leads as to the possible regional ancestry of the individual from whom a questioned hair originated.
