The Acheulean handaxe has always been considered a social phenomenon. Corbey et al.³⁵ provide a major challenge to this argument, arguing quite rightly, that it has never been independently established that handaxe temporal depth is a product of intergenerational social learning. They take a number of assumptions integral to the social argument and suggest, using parsimony, that a genetic explanation is equally as plausible for each of them. Complex structures, in hierarchically nested routines of action, can be built in the natural world by organisms following predetermined genetic sequences of actions triggered by external circumstances. However, there are some important points that the genetic argument dismisses that demonstrate an unequivocal social origin for the Acheulean handaxe. This article identifies those points and restores them to the debate. Parsimony affirms a social basis for handaxes and does not require a theoretical genetic predisposition.

关于手部遗传论证的进一步思考

Acheulean的手斧一直被认为是一种社会现象。Corbey等。³⁵正确地论证了这一观点的重大挑战，即从来没有独立地确定过轴时间深度是代际社会学习的产物。他们采用了社会论证中不可或缺的许多假设，并通过简约性提出了一种遗传解释对于它们中的每个都同样合理。在自然世界中，生物可以按照外部环境触发的预先确定的动作遗传序列，在层次结构嵌套的动作例程中构建复杂的结构。但是，遗传论据驳斥了一些重要的观点，这些事实表明了无针hand手斧的明确的社会起源。本文确定了这些要点，并将其恢复为辩论。
