Wiki: Caucasoid is a grouping of human beings historically regarded as a biological taxon, including some or all of the populations of Europe, North Africa, the Horn of Africa, Western Asia, Central Asia and South Asia. The term has been used in biological anthropology for many people from these regions, without regard necessarily to skin tone. First introduced in early racial science and anthropometry, the term denoted one of the three purported major races (Caucasoid, Mongoloid, Negroid) of humankind. Although its validity and utility are disputed by many anthropologists, Caucasoid as a biological classification remains in limited use in forensic anthropology.
EUROPE - Wiki: Geneticists have found that Europe is relatively genetically homogeneous. (Webster's - homogeneous: of the same or a similar kind or nature).
Wiki: Negroid is a grouping of human beings historically regarded as a biological taxon. The term has been used by forensic and physical anthropologists to refer to individuals and populations that share certain morphological and skeletal traits that are frequent among most populations in Sub-Saharan Africa.
Wiki: Mongoloid is a term now often deprecated as offensive, for peoples indigenous to East Asia, Central Asia, Southeast Asia, Eastern Russia, Northern Europe, the Arctic, the Americas, parts of the Pacific Islands, parts of Africa (Madagascar), and parts of South Asia. Individuals within these populations often share certain associated phenotypic traits, such as epicanthic folds (Epicanthus), sinodonty (Teeth type), and neoteny (Retention by adults of traits previously seen only in the young). [Mongols began settling the Pacific in modern times].
Epicanthal folds and oblique palpebral fissures are common among most Mongoloid individuals. Most exhibit Mongolian spot from birth to about age four. The vast majority have straight, black hair and dark brown almond-shaped eyes, and most have broad, relatively flat faces as well.
CHINA - The Han Chinese are an ethnic group native to East Asia. They constitute approximately 92% of the population of Mainland China, 93% of the population of Hong Kong, 92% of the population of Macau, 98% of the population of Taiwan, etc: and about 19% of the entire global human population, making them the largest ethnic group in the world.
Chromosome haplogroup O3 is a common DNA marker in Han Chinese, as it appeared in China in prehistoric times. It is found in more than 50% of Chinese males, and ranging up to over 80% in certain regional subgroups of the Han ethnicity. However, the mitochondrial DNA of Han Chinese increases in diversity as one looks from northern to southern China, which suggests that male migrants from northern China married with women from local peoples after arriving in Guangdong, Fujian, and other regions of southern China.
