DNA of old human feces found in a cave in Oregon (United States) contributes to the biological verification of people who lived 14000 years ago in North America, scientists said on Thursday.
The discovery, published in the journal Science, is added to the proofs for the existence of people living in America, before the date usually accepted by most of the researchers (13000 years ago), based on bones of the so-called Clovis culture in the Southwest of United States.
“The dates of the coprolites are more than 1,000 years earlier than currently accepted dates for the Clovis-complex”, the scientists wrote.
Dennis Jenkins, archaeologist of the University of Oregon, found the dry samples in caves known as Paisley Caves, about 350 kilometers to the southeast of Eugene, Oregon.
