It is speculated that it preceded the arrival of farmers moving from Anatolia into the Balkans and southern Europe. See https://doi.org/10.1038/s41562-022-01491-8 …
Archaeologists have uncovered projectile points in North America dating back 15,700 years ago – 3000 years older than Clovis fluted points. They were found in Idaho – well inland. The site is situated on traditional Nez Perce land, one of the most interesting of the India tribes. The points are said to be similar to projectile points found on Hakkaido Island in Japan, dating back 16,000 to 20,000 years ago. It seems to corroborate genetic and cultural connections between the Ice Age people of NE Asia and those of North America – or at least, some of them. The projectile points are characterised by two distinct ends. One is sharpened and the other is stemmed. They have a symmetrical beveled shape if looked at head on. They are small points that were probably attached to darts rather arrows or spears. Small projectile points mounted on darts would penetrate deeply, killing even large game. They were found in pits used for storage and food processing. The remains of an extinct horse was also found, presumably its bones, which is again interesting as the Nez Perce people were noted horse breeders and rearers.

Finally, at https://phys.org/news/2022-12-huge-year-old-mayan-civilization-northern.html …. which was sent in by Robert. A LiDAR survey of northern Guatemala has discovered a 2000 year old Mayan civilisation of around 1000 settlements, across 650 square miles. The settlements were connected by causeways – cleared and raised beds used as roads, or walkways. For more information see https://doi.org/10.1017/S0956536122000244 …
