Comment on 'Permanent human occupation of the central Tibetan Plateau in the early Holocene'

摘要

Meyer et al. (Reports, 6 January 2017, p. 64) suggest a new chronology for permanent human occupation of Tibet based on their dating of the travertine and colluvium deposits that contain or are deposited near fossil human handprints and footprints. However, misinterpretations in both stratigraphic reconstruction and dating data may have caused the newly proposed age of these human imprints to have been seriously underestimated.
