Story of human evolution gets another rewrite with DNA analysis of Chinese teeth

Fuyan cave in Daoxian County, Hunan province, China, is shown here. Scientists have dated teeth found inside the cave that suggest modern humans arrived in China less than 50,000 years ago.

(CNN)Experts hailed the discovery in 2015 as "stunning" -- 47 teeth found in a cave in southern China dated back to 80,0000 to 120,000 years ago, challenging widely accepted ideas about human evolution.

It suggested that Homo sapiens were in China at least 20,000 years earlier than early modern humans had been previously believed to have left Africa and spread around the world. It also tantalizingly hinted at the possibility that a different group of early humans could have evolved separately in Asia.
Not so fast, says the science in 2021. New research published Monday has suggested perhaps we shouldn't be so eager to rewrite the time line on human origins.
    DNA analysis of two human teeth found in the same cave, called Fuyan, plus teeth and other fossilized remains from four other caves in the same region, suggested that it was unlikely early modern humans were in China so early.
