Fig. 1 (IMAGE) Institute for Basic Science Caption Preferred habitats of Homo sapiens (purple shading, left), Homo heidelbergensis (red shading, middle), Homo neanderthalensis (blue shading, right) calculated from a new paleoclimate model simulation conducted at the IBS Center for Climate Physics and a compilation of fossil and archeological data. Lighter values indicate higher habitat suitability. The dates (1 ka = 1000 years before present) refer to the estimated ages of the youngest and oldest fossils used in the study.
