The acheulean handaxe: More like a bird's song than a beatles' tune?
Get PDFThe 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

crystal structures of americium species containing a common
multifunctional phosphine oxide ligand, reported for its ability to
extract f elements from acidic solutions, namely, 2,6-[Ph<sub>2</sub>P(O)CH<sub>2</sub>]<sub>2</sub>C<sub>5</sub>H<sub>3</sub>–NO, <b>L</b>, were finally determined after over three decades of separations
studies involving these species and their surrogates. The molecular
compounds Am(<b>L</b>)(NO<sub>3</sub>)<sub>3</sub>, <b>Am
1:1</b>, and [Am(<b>L</b>)<sub>2</sub>(NO<sub>3</sub>)][2(NO<sub>3</sub>)], <b>Am 2:1</b>, along with their neodymium and europium
analogues, were synthesized and characterized using single-crystal
X-ray crystallography, attenuated total reflectance Fourier transform
infrared spectroscopy, and luminescence spectroscopy to provide a
comprehensive comparison with new and known analogous complexes
