The Movius Line controversy: the state of the debate.

Patterns of Palaeolithic variability between eastern Asia and western portions of the Old World continue to engender controversial discussion. Most famously, debate has focused on variability in the absence/presence of 'handaxes' east and west of the so-called 'Movius Line'. However, it is becoming equally apparent that cross-regional contrasts can be made using categories of data other than handaxe presence/absence alone. This, in turn, is leading to a reconfiguration of the archaeological patterns that demand explanation. Here, we outline the current state of the Movius Line controversy in these terms, and undertake a series of metric analyses of eastern and western biface samples. This leads us to highlight specific lines of enquiry that may be important for future attempts to address these enduring questions. [ABSTRACT FROM AUTHOR]
