third ancestral group Japanese DNA
Definition
In population genetics, the 'third ancestral group' in Japanese DNA refers to a recently identified genetic component in modern Japanese populations, distinct from the well-known Jomon (ancient hunter-gatherers) and Yayoi (East Asian continental migrants) ancestries. This northeastern Asian-related group, often peaking in Tohoku and Okinawa regions, suggests additional migrations from groups like the Emishi or Siberian populations.
This 'hidden third ancestry' accounts for variations in disease risk and physical traits among Japanese people, as revealed by 2024 genomic studies analyzing over 3,000 individuals.
