The results of anthropological research show that the Bach Viet group first lived in Luong Quang, then moved north, east, and west, and finally expanded and developed in a large area south of Truong Giang. The first group of Bai Yue lived in Biguang, Bai Bo (百僕) lived in western Guangxi and Yunnan. San Miao (三苗) lived in northern Hubei, so the earliest expansion direction of Bach Yue was from the northeast and the main east. At least before the Ha Mau Du (河姆渡) culture, the ancient Vietnamese who migrated to the northeast entered Jiangxi, forming the Can Yue (干越) group later, some of which later moved to the west. most likely present-day Homo clan (侗族-Kam), which explains why the genetic structure of the Homo clan is classified as the Eastern European type (東甌). From Jiangxi to Zhejiang, the ancient Vietnamese formed the U Yue (於越) group, creating a brilliant civilization in the Ning Thieu (寧紹) and Taihu (太湖) plains. The ancient Vietnamese migrated eastward into Fujian and formed the Min Yue (閩越) tribe.
The latest molecular anthropology literature – Y-chromosome DNA can perform detailed analysis of ethnic systems. The Bach Viet system is said to be very different from other systems in China, and quite close to the Austronesian language group (Malay family), especially the Taiwanese language group. The Bach Viet populations that have been studied show genetic and linguistic and cultural differences that are related to the overall identity and geographical differences of Bach Viet. According to the principal component analysis of the data, there are three features of the genetic structure of the Bach Viet ethnic system.
1-Bach Viet has a single genetic group, possibly originating in Guangdong (thirty to forty thousand years ago) and spreading slowly.
2-Bai Yue is divided into two with Eastern Europe (東甌) with Zhejiang as the center, and Western Europe (西甌) with Ban Na as the center.
3- The extensive distribution of Bach Viet from Guangdong to Zhejiang through Jiangxi may have occurred very early. The Vietnamese group in Fujian and Zhejiang migrated in different ways, this duality is also present in the genetic makeup of the Taiwanese aborigines. The Tai group in Guangdong started to migrate very late.
Currently, the subject group of Bach Viet – Dong Tai, Nam Dao language family and Dong Tai language family are quite similar, and the Taiwanese language family is even closer, showing that Bach Viet group is closely related to the two groups. this group of people. The scope of genetics is not necessarily the same as linguistics and ethnography, groups derived from Bach Viet whose language and culture have changed should also be included in the Bach Viet domain. The Vietnamese group is in the east, the Taiwanese language group should be included in the study of Bach Viet. Although the Cao Miao group in the border areas of Hunan, Guangxi, and Guizhou speak the Dong language, the Miao mother’s Han and Han genetics are not part of the Bach Viet group.
According to genetic research, Bach Viet includes: Dong Tai language family, Dong Thuy language family, Ngot Uong language family, Le language family, Taiwanese indigenous peoples, Vietnamese descendants in the eastern region.
The Y-chromosome genetic makeup of these populations shows considerable consistency, and is quite different from populations studied in other systems. They all have a large number of M119, M110 or M95, M88 mutations, but outliers rarely have these genetic markers, and populations with little exposure to Bach Viet do not.
The Y-chromosome study of a large number of populations in the Asia-Pacific region plotted the relative tree of the ethnic system shown in (Figure 1).
Based on the genetic data of the Bach Viet populations collected, including the A Huo Mo (阿霍姆-India), Thai, Thai Lac (傣泐), Mu Lao, Mao Nam, Guangxi Zhuang clans , Ye Lang, Water Tribe, Dong Clan, Bo Yi and Shui in Guizhou, Le and Yilong (仡隆) in Hainan, Ma Gao in Shanghai, U Yue in Zhejiang, Taiya Aboriginal group in Taiwan , Bo Y, A My, Bai Loan, Lo Khai, Ty Nam, Thieu, the Y chromosome genetic structure of this population showed considerable consistency. They all have a large number of M119, M110, or M95, M88 mutations, while outliers rarely have these genetic markers, and populations with little exposure to Bach Viet do not.
On the other hand, the genetic relationships between these groups reflect a pattern different from the linguistic and ethnographic classifications. In particular, the two branches Dongshui (侗水) and Yi Yang (仡央) completely broke the culture and regrouped from the beginning. (Figure 2: circle is genetic relationship, dash is cultural classification)
The first main component accounts for 47% of the total information, looking at the structure, it is clear that the Bach Viet group is initially holistic in nature, so the bloodline has only one main source. The distribution center in the picture is Guangdong, so Guangdong is most likely the origin of the earliest Bach Viet bloodline. Then gradually expand to neighboring areas. (Figure 3)
The second major component accounted for 35.6% of total information, one in Zhejiang, two in Banna. Therefore, it was divided into binary characteristics after the Bach Viet people were in unity, differentiated into Eastern Europe and Western Europe.
