Ecological niche modelling is a method to predict presence of a given biological species by environmental parameters. It is also applicable to humans as eco-cultural niche modelling (ECNM) under the condition that the human behaviour significantly depends on the natural environment [1]. There are two methods of ECNM--Genetic Algorithm for Rule-set Production (GARP) [2] and Maximum Entropy Model (Maxent) [3]. Both models require geocoordinates of archaeological sites and environmental variables such as terrain elevation, slope, mean temperature, and annual precipitation. GARP outputs prediction in binary [0,1], while Maxent outputs in continuous probability [0...1]. This paper applies these predictive models to two case studies: 1) the replacement of Neanderthals by anatomically modern humans in the Levant, and 2) the subsistence economy of Jomon hunter-gatherer-fishers in East Japan. Then validity of the models is discussed and a hybrid model based on the two models is proposed for better predicting and visualising site presence. [1] Banks, W. E. et al. 2008.
