摘要：SummaryWithin comparative psychology, the evolution of animal cognition is typically studied either by comparing indirect measures of cognitive abilities (e.g., relative brain size) across many species or by conducting batteries of decision-making experiments among (typically) a few captive species. Here, we propose a third, complementary approach: inferring and comparing cognitive abilities through observational field records of natural information gradients and the associated variation in decision-making outcomes, using the ranging behavior of wild animals. To demonstrate the feasibility of our proposal, we present the results of a global survey assessing the availability of long-term ranging data sets from wild primates and the willingness of primatologists to share such data. We explore three ways in which such ranging data, with or without the associated behavioral and ecological data often collected by primatologists, might be used to infer and compare spatial cognition. Finally, we suggest how ecological complexity may be best incorporated into comparative analyses.Graphical abstractDisplay OmittedHighlights•Comparing animal ranging decisions in natural habitats has untapped potential•How decisions vary with natural information gradients reveals wild animal cognition•Ranging data on at least 164 populations of 105 wild primate species are available•We present three thought analyses to compare cognition and explain its evolutionBiological Sciences; Neuroscience; Cognitive Neuroscience
