Selection-Driven Range Expansion Explains Lapita Colonisation of Remote Oceania
Author(s): Ethan Cochrane
Archaeological explanations of colonization often focus on presumed human motivations. What drives humans when faced with the potentially risky and rewarding colonization of unoccupied island regions: curiosity, wanderlust, opportunity, escape? At best, human motivation is only a partial explanation for colonization and one that is difficult to evaluate with archaeological data. In contrast, archaeologically visible, population-scale patterns of human colonization are explicable by the natural and social environment, transmission and selection. This paper develops a range-expansion hypothesis from animal ecology and evolution to explain Lapita colonisation of Remote Oceania. The hypothesis is tested with both archaeological data and simulation modelling.
