Two articles, one published in the journal “Cell” and one in the journal “Science”, describe two exams conducted on the so-called Harbin Cranium, a fossil discovered in Manchuria, northeastern China, dated at least 146,000 years old. A team of researchers led by paleogeneticist Qiaomei Fu of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing and Qiang Ji of Hebei University recovered fragments of mitochondrial DNA from the dental calculus still present on the skull and proteins.
