It’s a breezy, yet warm day on Santa Rosa Island. At the site of a historic ranch house, archeologists found artifacts which show that humans were here more than 10,000 years ago.
The finds support evidence that some of the oldest known human existence in North America was in the Channel Islands. University of Oregon archeologist Jon Erlandson has been studying the islands for four decades. He says the researchers have also discovered evidence of something else related to humans: global warming.
