The Acheulean handaxe: More like a bird's song than a beatles' tune?

The goal of this paper is to provoke debate about the nature of an iconic artifact-the Acheulean handaxe. Specifically, we want to initiate a conversation about whether or not they are cultural objects. The vast majority of archeologists assume that the behaviors involved in the production of handaxes were acquired by social learning and that handaxes are therefore cultural. We will argue that this assumption is not warranted on the basis of the available evidence and that an alternative hypothesis should be given serious consideration. This alternative hypothesis is that the form of Acheulean handaxes was at least partly under genetic control.

Comment on "Late Mousterian persistence near the Arctic Circle".

Slimak et al. (Reports, 13 May 2011, p. 841) reanalyzed the lithic assemblage from the northern site of Byzovaya (Russia) and concluded that it was Mousterian and produced by Neandertals. The previous interpretation of this assemblage as falling within Early Upper Paleolithic variability remains the most parsimonious explanation; pending additional fossil discoveries, there is no evidence supporting the occurrence of Neandertals at these high latitudes.

Direct terrestrial-marine correlation demonstrates surprisingly late onset of the last interglacial in central Europe.

An interdisciplinary study of a small sedimentary basin at Neumark Nord 2 (NN2), Germany, has yielded a high-resolution record of the palaeomagnetic Blake Event, which we are able to place at the early part of the last interglacial pollen sequence documented from the same section. We use this data to calculate the duration of this stratigraphically important event at 3400 ± 350 yr. More importantly, the Neumark Nord 2 data enables precise terrestrial-marine correlation for the Eemian stage in central Europe. This shows a remarkably large time lag of ca. 5000 yr between the MIS 5e 'peak' in the marine record and the start of the last interglacial in this region.
