== Definition and Evolutionary History ==
The '''Mongolid''' (or '''East Eurasian''') race is a historical anthropological term used to classify the indigenous populations of East Asia, Central Asia, Southeast Asia, the Arctic, and the Americas. Genetic evidence suggests that East Eurasians diverged from West Eurasians approximately 40,000 to 50,000 years ago.<ref>[https://www.nature.com/articles/s41467-021-21355-w The genomic history of East Asia - Nature Communications]</ref>

The "classic" Mongolid phenotype—characterized by the epicanthic fold, high cheekbones, and straight black hair—is often cited as one of the most specialized in human history. These traits likely evolved in the extreme cold of the Pleistocene mammoth steppe. The fatty eyelids (epicanthic fold) provided insulation for the eyes and protection against the blinding glare of snow and wind-driven ice. As these populations moved south and east, they adapted to every climate on Earth, from the tropical rainforests of the Amazon to the high-altitude Andes.<ref>[http://humanphenotypes.net/basic/Mongolid.html Human Phenotypes: Mongolid Morphology]</ref>

== Mongolid Types ==

=== Ainuid ===
Typical for the '''Ainu''', the indigenous people of northern Japan and Sakhalin.
* '''Aoshima (Ainuid proper)''': Historically, the Ainu were a major mystery to anthropologists because they possessed "pseudo-Caucasoid" features like heavy beard growth and deep-set eyes. Modern genetics shows they are descendants of the ancient '''Jomon''' hunter-gatherers, representing a "Paleo-Mongoloid" lineage that inhabited Japan before the arrival of rice-farming Yayoi groups.<ref>[https://www.sciencedirect.com/science/article/pii/S187249731630222X Genetic origins of the Ainu - Forensic Science International]</ref>

=== Tungid ===
Typical for the Tungusic and Mongolic speakers of North and Central Asia.
* '''Gobid (Tungid proper)''': Common in Mongolia. This type represents the "classic" steppe warrior phenotype.
* '''Tungid-Turanid''': A significant mixture between East Eurasians and West Eurasians (Europoids) found along the Silk Road. Subtypes like the '''Aralid''' and '''Transcaspian''' are common in Kazakhstan and Kyrgyzstan, reflecting the deep history of migration and empire-building in Central Asia.<ref>[http://humanphenotypes.net/Tungid.html Human Phenotypes: Tungid]</ref>

=== Sibirid (The Arctic Adaptation) ===
Typical for the indigenous peoples of northern Russia and the Arctic.
* '''West Sibirid''': Includes the '''Uralid''' and '''Samoyedic''' types, showing a ancient cline of mixture between European and Siberian groups.
* '''East Sibirid (Eskimid/Arctid)''': This group includes the '''Inuit''' and '''Chukchi'''. They possess the most extreme cold adaptations, such as short limbs to conserve heat (Allen's Rule) and high metabolic rates to process a diet rich in seal and whale blubber.<ref>[https://www.science.org/doi/10.1126/science.aab2319 Genetic adaptation to extreme cold and diet in Greenlandic Inuit - Science]</ref>

=== Sinid (East Asian Core) ===
Typical for the populations of China and Korea.
* '''Huanghoid (North Sinid)''': Associated with the expansion of millet farming in the Yellow River valley. They are generally taller and narrower-faced than southern groups.
* '''West Sinid''': Found in central and western China, often showing higher phenotypic variation due to the rugged terrain and ancient trade routes.

=== South Mongolid ===
Associated with Southeast Asia, these types show adaptations to humid, tropical environments.
* '''Continental South Mongolid''': Typical for the populations of Indochina (Thailand, Vietnam).
* '''Insular South Mongolid''': Found in the Philippines, Malaysia, and Indonesia. This phenotype often features wider noses and fuller lips compared to northern Sinids.

=== Polynesid ===
Typical for the seafaring populations of the Pacific (Polynesians).
* The Polynesid type is a remarkable "New World" creation of the sea. They are robust and tall, an adaptation believed to prevent hypothermia during long-distance voyaging across the Pacific. They represent a mixture of East Asian seafaring DNA with ancient Melanesian (Australoid) lineages.<ref>[https://www.nature.com/articles/nature21420 Genome-wide ancestry patterns in Oceania - Nature]</ref>

== Amerindian Types (The Great Migration) ==
Amerindians represent the populations that crossed the '''Bering Land Bridge''' during the last Ice Age. Despite a shared origin, they diversified into dozens of localized phenotypes.

* '''Pacifid''': Found along the Northwest Coast of North America (e.g., Haida, Tlingit).
* '''Silvid''': Typical for the forest tribes of North America (e.g., Iroquois, Cherokee).
* '''Margid''': An older, more robust type found in isolated pockets of California and Mexico.
* '''Centralid''': Associated with the civilizations of Mesoamerica (Aztecs, Maya).
* '''Amazonid''': Typical for the indigenous peoples of the Amazon rainforest.
* '''Andid''': A specialized high-altitude phenotype of the Andes (Inca), characterized by massive lung capacity and barrel chests to breathe the thin mountain air.<ref>[https://www.science.org/doi/10.1126/sciadv.aau4921 The genetic prehistory of the Andean highlands - Science Advances]</ref>
* '''Lagid''' and '''Patagonid''': Found in the southern cone of South America, including the tall, robust hunters of the Patagonian plains.

== Global Impact and Synthesis ==
The Mongolid phenotype's spread is the story of human resilience. From the development of the first agricultural systems in the East to the complex astronomical civilizations of the Americas, these groups have shaped the course of human history. Today, the "East Eurasian" genetic legacy is the most populous on the planet, driving global innovation and cultural exchange in the 21st century.
