Dating prehistoric remains

Cody Martinez, tribal chairman of the Sycuan Band of the Kumeyaay Nation, said the discovery is consistent with traditional beliefs that the Kumeyaay have lived in the area, “since time immemorial.”“It’s really neat, to have a find like that,” Martinez said.

“It’s an exciting surprise and definitely does fit in line with the traditional creation story of the Kumeyaay people.”Natural History Museum President and CEO Judy Gradwohl, who came from a previous post at the Smithsonian Institution in Washington, D.

Recent developments in that process allow them to analyze the isotope ratios more accurately over smaller samples, Pace said.

He painstakingly studied samples across the bones, and came up with a date of 130,000 years old, plus or minus 9,400 years.

The dates reported in this study form the biggest set of direct dates on rock art in South Africa and the only direct dates ever obtained in Botswana and Lesotho.

Lead author, Bonneau, concludes in the paper: "This protocol is a step forward in the field of rock art dating by reducing the sample size to be collected, by optimising the success rate of such dating, and by limiting the impact on such valuable paintings while providing new chronological insights."

C., said it’s not hard to see why people could have migrated to the temperate, coastal region thousands of centuries ago.“As a recent transplant to this region, my personal conclusion about this research is that even early humans wanted to live in San Diego,” she said.

The findings rewrite the story of human expansion to the New World, scientists said, and illuminate the wanderlust that drove ancient people to test the boundaries of their world.“Humans, we’re curious,” said Tom Demere, a co-author of the study and curator of paleontology for the San Diego Natural History Museum. Early on, paleontologists suspected that something didn’t add up.This finding has profound implications for our understanding of hunter-gatherer religion in southern Africa." Research was conducted in the Thune Dam in Botswana, the Metolong Dam area in the Phuthiatsana Valley of Lesotho, and the Drakensberg Escarpment of the Eastern Cape in the 'Nomansland' region of South Africa.A total of 43 new dates were produced from these three areas, including the first direct dates on rock paintings ever in Botswana and Lesotho.In a study published in the international journal Antiquity, Professor David Pearce, Director of the Rock Art Research Institute at the University of the Witwatersrand, Johannesburg, Adelphine Bonneau of Laval University, Canada, and colleagues at the University of Oxford showed that paintings in south-eastern Botswana are at least 5500 years old, whilst paintings in Lesotho and the Eastern Cape Drakensberg, South Africa, date as far back as 3000 years.The findings represent a major breakthrough in archaeological research.
