Archaeological evidences are still missing: a comment on Fari?a et al. Arroyo del Vizcaíno site, Uruguay

摘要

Fari?a et al. [1] suggest the possibility of human presence ca 30 ka in the Arroyo del Vizcaíno site (AVS) (southern Uruguay). This is based mainly on the record of cutmarks made by human artefacts on Pleistocene animal bones. They also inform of the finding of a single tiny stone tool and few other possible lithic artefacts. Nevertheless, their research has serious methodological problems and important interpretative errors.
