Ecological niche models have found many applications in paleoecology, archeology and paleoanthropology. These models are based on niche theory and are used to model the distribution of species through time and space. Species distribution models use species distribution data and environmental predictors to model species distribution. In this study I used MaxEnt model, distribution records of the Homo neanderthalensis (Mousterian artefacts) and topographic and climatic data to reconstruct eco-cultural niche of the species on the Central Iranian Plateau. The performance of the model was assessed using the area (AUC) under the receiver operating curve (ROC). The predictive ability of the model was high (AUC = 0.827 for training and 0.813 for test data). The species past distribution model showed that there were numerous suitable patches for distribution of the species in the study area. The most continues patches were found in Yazd province, west of Semnan province and east of Isfahan province. With 48.3 percent contribution to the model, topographic heterogeneity was the most important predictor of this archaic human distribution. This is because topographic heterogeneity influences resource availability, meaning that areas with higher topographic heterogeneity provide more resources. The eco-cultural niche model predicts many suitable patches which can be target of future field excavations in the study area.
