The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period,[1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent between 26,000 and 20,000 years ago.[2] Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts,[3] along with a large drop in sea levels.[4]

I wonder if Europeans have any Gravettian and/or Solutrean ancestry apart from this mediated by ANE.

ANE was a mixture of roughly 2/3 Gravettian and roughly 1/3 Tianyuan-like, if I remember correctly.
