A study led by researchers at the Nagoya University Museum in Japan may change how we understand the cultural evolution of Homo sapiens at the time of their dis
The neutral model of stone procurement developed by Brantingham (2003, 2006) provides a formal means to investigate the formation of lithic discard patterning under changing forager mobility conditions. This study modifies Brantingham's (2006) Lévy walk model to examine the influence of discard probability on the spatial distribution of raw material abundance. The model outcome shows that forager movement and tool discard probability have similar effects on the simulated patterns of raw material transport, so it is difficult - if not impossible - to differentiate the respective influence...
