Abstract

Ancient Weaponry: Hafting, which allowed projectile points to be attached to a staff, was an important technological advance that greatly increased the functionality of weapons of early humans. This technology was used by both Neandertals and early Homo sapiens and is readily seen after about 200,000 to 300,000 years ago, but whether it was used by a common ancestor or was separately acquired by each species is unclear. Supporting use by a common ancestor, Wilkins et al. (p. 942 ) report that stone points in a site in central South Africa were hafted to form spears around 500,000 years ago. The evidence includes damaged edges consistent with this use and marks at the base that are suggestive of hafting.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
