Recently discovered remains could take modern humans back more than 300,000 years.
When experts in China unearthed what they say could be the world's oldest anatomically modern human remains ever discovered, it would have seemed natural to ask: How can they be so sure? 300,000 years ago, perhaps. How do they know?
Hualong Cave No. 6 compared to the position of the perforation in the hard palate of other ancient human fossils. Researchers say using the teeth from the fossil may be the best way to accurately date it without destroying it."This would be a destructive process though, so it is clearly not advisable," he said. Instead, he said to look to human teeth to be as sure as one can ever get in human dating accuracy.
"The comparative analysis of modern human specimens resulted in a series of new discoveries and understandings," Liu Wu said.
