Peștera cu Oase fossil shows recent Neanderthal admixture. Peștera cu Oase jaw from Romania dates to around 40,000 years ago This individual had a Neanderthal ancestor 4-6 generations earlier (approximately 200 years) The Oase 1 individual had 6-9% Neanderthal ancestry, higher than modern non-Africans (~2%)

The 40‑kyr‑old Peștera cu Oase jaw from Romania carries 6‑9%% Neanderthal DNA, with three long segments (50 cM) indicating a Neanderthal ancestor just 4‑6 generations back – a striking contrast to the tiny, fragmented Neanderthal fragments in modern non‑Africans.

Key Facts

  • Peștera cu Oase jaw from Romania dates to around 40,000 years ago
  • This individual had a Neanderthal ancestor 4-6 generations earlier (approximately 200 years)
  • The Oase 1 individual had 6-9% Neanderthal ancestry, higher than modern non-Africans (~2%)
  • Researchers identified three Neanderthal DNA segments over 50 centimorgans in length
  • The length of these segments indicates recent interbreeding rather than ancient admixture
  • Modern humans carry many small fragmented Neanderthal DNA segments from thousands of generations of recombination
  • An estimated 20-40% of the Neanderthal genome survives in modern humans
