Editing Hlai people (section)

==Genetics==
The Hlai are believed to be descendants of the [[Rau people]], who settled on the island thousands of years ago.<ref>{{Cite encyclopedia|url=https://www.britannica.com/topic/Li-Asian-people|title=Li {{!}} Asian people|encyclopedia=Encyclopedia Britannica|access-date=24 October 2018|language=en}}</ref> [[DNA analysis]] carried out amongst the modern Hlai population indicate a close relationship with populations in the southern Chinese province of [[Guangxi]].<ref name="BMC Evolutionary Biology"/> Most of them have Y-DNA O1a and O1b.

A 2019 study states that the Hlai show genetic affinities with Tai-Kadai-speaking groups (i.e. [[Zhuang people|Zhuang]] and [[Dong people|Dong]]) and Hmong-Mien-speaking groups (i.e.[[Miao people|Miao]] groups). In contrast, Han Chinese in Guangxi show affinities with [[Tujia people|Tujia]], [[Bai people|Bai]], [[She people|She]] and Sinitic-speaking populations.<ref>{{Cite journal |last=Liu |first=Jing |last2=Ye |first2=Ziwei |last3=Wang |first3=Zheng |last4=Zou |first4=Xing |display-authors=3 |date=2019 |title=Genetic diversity and phylogenetic analysis of Chinese Han and Li ethnic populations from Hainan Island by 30 autosomal insertion/deletion polymorphisms |url=https://www.tandfonline.com/doi/full/10.1080/20961790.2019.1672933#summary-abstract |journal=Forensic Sciences Research |volume=7 |issue=2 |via=Taylor & Francis Online}}</ref> A 2022 study shows that Hlai are enriched with ~85% Baiyue ancestry due to their geographic isolation. But there is evidence of admixture between Hlai and Han Chinese about 2000 years ago, with Hlai having about 56.56% Han ancestry as a result. In addition, there is evidence that the [[Kinh Vietnamese]] diverged earlier from the Hlai than the [[Dai people|Dai]] diverged from Hlai.<ref>{{Cite journal |last1=Chen |first1=Hao |last2=Lin |first2=Rong |last3=Lu |first3=Yan |last4=Zhang |first4=Rui |display-authors=3 |date=2022 |title=Tracing Bai-Yue Ancestry in Aboriginal Li People on Hainan Island |journal=Molecular Biology and Evolution |volume=39 |issue=10 |doi=10.1093/molbev/msac210 |pmc=9585476 |pmid=36173765 |via=Oxford Academic}}</ref> Other studies likewise suggest that the [[Longli County|Longli]] [[Bouyei people|Bouyei]] and [[Qiandongnan Miao and Dong Autonomous Prefecture|Qiandongnan]] [[Dong people|Dong]], whom Kinh Vietnamese cluster with, could be described as a good representative of the 'ancestral Tai-Kadai' population.<ref name=":4">{{cite report |title=New insights from the combined discrimination of modern/Ancient genome-wide shared alleles and haplotypes: Differentiated demographic history reconstruction of Tai-Kadai and Sinitic people in South China |last1=Wang |first1=Mengge |last2=He |first2=Guanglin |last3=Zou |first3=Xing |last4=Chen |first4=Pengyu |last5=Wang |first5=Zheng |last6=Tang |first6=Renkuan |last7=Yang |first7=Xiaomin |last8=Chen |first8=Jing |last9=Yang |first9=Meiqing |last10=Li |first10=Yingxiang |last11=Liu |first11=Jing |last12=Wang |first12=Fei |last13=Zhao |first13=Jing |last14=Guo |first14=Jianxin |last15=Hu |first15=Rong |date=2021 |doi=10.1101/2021.06.19.449013 |type=Preprint |last16=Wei |first16=Lan-Hai |last17=Chen |first17=Gang |last18=Yeh |first18=Hui-Yuan |last19=Wang |first19=Chuan-Chao}}</ref>
