The 10kTrees website: A new online resource for primate phylogeny

The comparative method plays a central role in efforts to uncover the adaptive basis for primate behaviors, morphological traits, and cognitive abilities.1-4 The comparative method has been used, for example, to infer that living in a larger group selects for a larger neocortex,5, 6 that primate territoriality favors a longer day range relative to home range size,7 and that sperm competition can account for the evolution of primate testes size.8, 9 Comparison is fundamental for reconstructing behavioral traits in the fossil record, for example, in studies of locomotion and diet.10-13 Recent advances in comparative methods require phylogenetic information,2, 14-16 but our knowledge of phylogenetic information…
