Is this what killed off the Clovis culture? [View all]
One of the oldest American Indian peoples are the Clovis people, recognized for among other things their distinctive spear points. They disappeared around 12000 years ago.
https://penetrate.blogspot.com/2009/01/what-killed-off-clovis-people.html has this quote:
"What killed off the Clovis people. Tiny diamonds found in the soil are "strong evidence" a comet exploded on or above North America nearly 13,000 years ago, leading to the extinction of dozens of mammal species, according to a study"
I just saw some news that may be related: a 19-mile wide impact crater has been discovered, under the Greenland ice cap. It apparently dates to around 12000 years ago. See https://www.theguardian.com/science/2018/nov/14/impact-crater-19-miles-wide-found-beneath-greenland-glacier
The timing seems interesting. Could this be what killed off this early culture? Could other cultures around the world have been affected at about the same time?
This kind of science is not my area. Are there DU readers who know this area who can comment here?
