DNA from 2m years ago reveals lost Arctic world

200万年前的古老DNA揭示了失落的北极世界

英语原文:

Two-million-year-old DNA from northern Greenland has revealed that the region was once home to mastodons, lemmings and geese, offering unprecedented insights into how climate change can shape ecosystems. The breakthrough in ancient DNA analysis pushes back the DNA record by 1m years to a time when the Arctic region was 11-19C warmer than the present day. The analysis reveals that the northern peninsula of Greenland, now a polar desert, once featured boreal forests of poplar and birch trees teeming with wildlife. The work offers clues to how species might adapt to survive the threat of rapid global heating.
