"Archaeologists say human-evolution study used stolen bone"
In a letter initiated by Wil Roebroeks, among others, serious concerns were raised about three research papers claiming evidence for one of the earliest human occupations of Europe.
The writers of the letter allege that the papers, published in 2013, 2016 and 2017, included material of questionable provenance, and that results reported in the 2016 paper were based on at least one stolen bone. Editors at the journals concerned have now published expressions of concern about the papers.
