But the analytics were not made in China or by a Chinese researcher. So unless they tampered with the skull's age somehow, they would have little influence here.
Twelve of the paper's thirteen authors (all except Chris Stringer) are shown as working in China according to https://www.science.org/doi/10.1126/science.ado9202 (click "Authors Info & Affiliations" near the top), and the research was funded by the National Natural Science Foundation of China.
To be clear I don't mean to imply anything about possible biases or ulterior motives or whatnot. I was merely responding to "the analytics were not made in China or by a Chinese researcher" (which seems factually incorrect, unless I misunderstood something).
