The Minnan speaking people (Hokkiens) being genetically more Han Chinese than the Hakkas? How can that be? Hakka people started arriving from north/central China to Fujian beginning from the 12th century. By that time of their arrival, the region was already inhabited by the Minnan people who are themselves an intermix of Han people who had migrated centuries earlier and the native Min Yue people. The Hakkas built those circular earthen buildings (tulou) to house their large multi-family and do not mix much with the locals. The Hakkas have a stronger Han heritage on account of being late arrivals and they certainly do not carry as much genes of the natives/aborgines of south China compared to people who had arrived earlier.
Didn't you read the genetic graph on the first page? Hakka is only more northern than Cantonese. In Guangdong, Teochew is most Han Chinese, than Hokkien, than Hakka and Cantonese. But like I said any other Southern Chinese province (aside from Guangxi and Fujian) is already more northern Chinese than any Teochew and Hokkien. So even if Hakka are more northern Chinese than teochew it would still make you very southern Chinese. The historic evidence that your Hakka claimed to be pure north Chinese it not backed up by any modern genetic evidence and these study are done by Chinese scientists . Some Hakkas are even sinicized aborigines not of Han Chinese origin.
YOU CLAIM THAT YOU DID NO MIXED WITH THE LOCALS? Here is an 2nd study of mtDNA maternally inherited DNA. It shows Hakka maternal DNA is dominated by southern aborigines.

[Abstract] the purpose of the Guangdong Department of the Han people or three large Chaoshan, Cantonese and Hakka are the descendants of landlocked Central China the Han immigrants, this study reflect the maternally inherited mitochondrial DNA (mtDNA) evidence of three major differences between the people of the genetic backgrounds . Chaoshan blood samples were collected 89 and 48 landlocked Central Plains high incidence of esophageal cancer among blood Taihang Mountain to build each individual's mtDNA haplogroups; Cantonese and Hakka haplogroup data from the literature. these 3 Department of a large crowd of people haplogroups and the distribution of population and the south of Taihang Mountain comparative analysis of Aboriginal people. Results Taihang Mountain Han people mainly from the north constitute the major haplogroups, Cantonese and Hakka, Aborigines South Main Zeyi haplogroup mainly Chaoshan showed major haplogroups in northern Han slightly above the main indigenous southern haplogroups. haplogroups based on the frequency of the principal component analysis, together Taihang Mountain and Chaoshan,
Hakka and Cantonese people are aboriginal groups and the South together. Conclusion 3 large public system,
only the Han nationality Chaoshan blood is more pure, and the closest Taihang Mountain population,.
