Ancient DNA in Greenland Dirt Reveals Dramatic Warming and Lost Wildlife

#AncientDNA #ClimateChange #ArcticWarming Ancient DNA in Greenland Dirt Reveals Dramatic Warming and Lost Wildlife In December 2022, a team led by Eske Willerslev and Kurt H. Kjaer announced the recovery of authentic 2-million-year-old environmental DNA from permafrost sediments at Kap Kobenhavn in northern Greenland, shattering previous age records and redefining what is technically possible. Molecular traces revealed a vanished forest ecosystem, ancestral megafauna, and Arctic temperatures up to 19 degrees warmer than today, all preserved in ordinary clay and smectite minerals.
