Except that the extinctions overwhelming occurred in North America rather than the other populated continents. I suspect one or more impact events, myself...
Agreed. The article title and conclusions are totally misleading.
The vast majority of the extinctions can be directly traced to whatever happened 11,000 years ago.
This would be like blaming high deer mortality on the falling leaves in the fall and ignoring the guys out there who happen to have guns...
More “Publish or Perish”...
Even if it’s dreck...
North America lost the most because it had the most (or we just currently know of more species), but Australia and South America also lost all of their large mammals.
The pattern is clear, whenever man showed up large mammals start to go extinct.
I suspect one or more impact events, myself...
yes impacts are really, really cool, but unless just by some amazing coincidence that whenever man showed up an impact just happened to always occur in the same exact location the impact(s) hypothesis doesn't make sense.
