@militaryhistori According to medieval sources, Brythonic was still spoken in East Anglia and The Fens as late as 10th century. Interesting short video: https://t.co/ynhLdZDuQe

AI synopsis
What people are saying
The collective discussions reflect a strong interest in the detailed genetic research, with users citing sources like Leslie et al. (2015), and debating the implications of ancient Briton DNA on modern identity; the tone ranges from analytical to asserting historical continuity, showing deep engagement and a recognition of the study's significance in understanding British origins.
Most discussions support the findings of the study, emphasizing the deep genetic roots of the British population and challenging recent migration narratives.
Posts demonstrate a strong curiosity about the genetic history and regional differences within Britain, referencing specific studies and historical contexts.
Many users actively cite sources, analyze the data, and discuss implications, indicating profound engagement with the research.
The discussions have the potential to influence perceptions of British identity and challenge simplified narratives about ethnicity and migration, though some comments are more informational than action-driving.
Abstract in brief
- The study analyzes fine-scale genetic differences within the British population using haplotype-based methods on genome data from 2,039 individuals, revealing detailed regional genetic patterns that closely match geographic locations.
- It identifies that these regional genetic differences reflect historical events, such as Anglo-Saxon migrations contributing less than half to southeastern England's genetics and evidence of earlier movements from continental Europe post-Mesolithic period.
- The research also shows that outside of Saxon-influenced areas, the UK consists of genetically distinct subgroups rather than a single homogeneous Celtic population.]

There were saxon rulers with Celtic sounding names like Cerdic so it may also be that some Britons had taken on the culture and ruled kingdoms. Also check this video out for more. It talks about the last Celts in England. https://t.co/A37CVjDndL
