Journeys in space and time: assessing the link between Acheulean handaxes and genetic explanations
In a recent paper Corbey and colleagues argued that there may be a genetic component to Acheulean handaxe manufacture across the Old World. They mention innovative work by Stephen Lycett and Noreen von Cramon-
Taubadel who argued that assemblages of handaxes will show less handaxe shape variability the further they are away from Africa. This is because handaxe shape conforms to a genetic model of loss of diversity resulting from
serial bottlenecking. The model linked material culture to hominin demography. Here I argue that there is no loss of shape with time and geographical distance from Africa, merely a tacking of outline form across potential
morphological space as a result of a number of different factors which will vary with place and time. I use a

this.

Abstract

In a recent paper Corbey and colleagues argued that there may be a genetic component to Acheulean handaxe manufacture across the Old World. They mention innovative work by Stephen Lycett and Noreen von Cramon-
Taubadel who argued that assemblages of handaxes will show less handaxe shape variability the further they are away from Africa. This is because handaxe shape conforms to a genetic model of loss of diversity resulting from
serial bottlenecking. The model linked material culture to hominin demography. Here I argue that there is no loss of shape with time and geographical distance from Africa, merely a tacking of outline form across potential
morphological space as a result of a number of different factors which will vary with place and time. I use a
modified version of Lycett and von Cramon-Taubadel's methodology, and 2D geometric-morphometrics to show
this.
