Fossils challenge dna in the dating game
The mandible, unearthed by paleontologists in Zhiren Cave in Guanxi Province in southern China in 2007, sports a distinctly modern feature: a prominent chin.The fossil was called "the oldest modern human outside of Africa," by study co-author Erik Trinkaus, an anthropologist at Washington University in St. [Source: Rachel Kaufman, National Geographic News, October 25, 2010 | “The skeleton from China, for example, has a genetically determined dental feature common in Neanderthals that is not present in early modern humans from Africa.“We are not quite sure whether those [bite marks] were from predators or other humans,” researcher Li Zhanyang told China Daily.Sixteen pieces of a skull known as Xuchang Man that still bore traces of a fossilized membrane were recovered from the site in 2008.[Source: China’s Museums] In July 2015, Archeology magazine reported; The 100,000-year-old remains of at least nine individuals have so far been unearthed at the Lingjing Historical Site in central China by a team from the Henan Provincial Institute of Cultural Relics and Archaeology.Two of the limb bones, which may have belonged to the same young individual, carry bite marks.
DNA-testing of haplogroup B in 2013 revealed that he was related "to many present-day Asians and Native Americans..had already diverged genetically from the ancestors of present-day Europeans".
"The problem is that we lack decent samples of early modern humans from Africa between [40,000 and] 80,000 years ago," he commented in an email.
But the appropriate skeletal evidence is not yet represented in the fossil record, he said.
It is believed that Mountaintop Cave Man sewed and clothed himself with animal hides and leather.
Among the other objects found at the site have been earrings, animal teeth with holes in them for stringing, fishbones, ocean shells, stone beads, and bones carved in particular ways.
