A new theory on the origin of primates was published on Zoologica Scripta. The paper, Evolution and biogeography of primates: a new model based on molecular phylogenetics, vicariance and plate tectonics by Michael Head, argues that the distribution of major primate groups are correlated with the Mesozoic tectonic features. The range of these primate groups correspond to them evolving locally from a widespread ancestor on the supercontinent of Pangea about 185 million years ago.
