Scientists say the patterns of breakage in mastodon bones found 25 years ago near a San Diego highway suggest that humans battered the beast 130,000 years ago.
That’s a shocker, because before now, the oldest widely accepted evidence of human habitation in North America goes back only about 16,000 years. If the scientists are right, that makes the place they studied, known as the Cerutti Mastodon site, the oldest archaeological site in North America.
The U.S. Army Corps of Engineers has just ruled that an 8,500-year-old set of skeletal remains known as Kennewick Man or the Ancient One belonged to a Native American tribe, based on DNA tests that came out nearly a year ago.
It took that long for experts to weigh the genetic evidence, plus other anatomical evidence that has been the focus of a 20-year-long legal tug of war. Earlier this month, a trio of scientists from the University of Chicago issued a technical report declaring that the DNA findings published last June in Nature were sound.
The remains were found on the banks of the Columbia River near Kennewick, Wash., in 1996. Five Pacific Northwest tribes pressed the Army Corps of Engineers, which has jurisdiction over the bones, to hand them over in accordance with a federal law on the repatriation of remains. However, a group of scientists sued to block the handover, arguing that the skeleton was not associated with a present-day tribe.
