      New World monkeys display a wide range of masticatory apparatus morphologies related to their diverse diets and feeding strategies. While primatologists have completed many studies of the platyrrhine masticatory apparatus, ...
    • Auditory morphology and hearing sensitivity in fossil New World monkeys. 

      Coleman, M; Kay, RF; Colbert, MW (Anatomical record (Hoboken, N.J. : 2007), 2010-10)
      In recent years it has become possible to investigate the hearing capabilities in fossils by analogy with studies in living taxa that correlate the bony morphology of the auditory system with hearing sensitivity. In this ...
    • Avian brains and a new understanding of vertebrate brain evolution. 

      Jarvis, Erich D; Güntürkün, Onur; Bruce, Laura; Csillag, András; Karten, Harvey; Kuenzel, Wayne; Medina, Loreta; ... (30 authors) (Nat Rev Neurosci, 2005-02)
      We believe that names have a powerful influence on the experiments we do and the way in which we think. For this reason, and in the light of new evidence about the function and evolution of the vertebrate brain, an international ...
    • Barnacle cement: a polymerization model based on evolutionary concepts. 

      Dickinson, Gary H. (2009-11)
      The tenacity by which barnacles adhere has sparked a long history of scientific investigation into their adhesive mechanisms. To adhere, barnacles utilize proteinaceous cement that rapidly polymerizes and forms adhesive ...
    • Behaviourally driven gene expression reveals song nuclei in hummingbird brain. 

      Jarvis, ED; Ribeiro, S; da Silva, ML; Ventura, D; Vielliard, J; Mello, CV (Nature, 2000-08-10)
      Hummingbirds have developed a wealth of intriguing features, such as backwards flight, ultraviolet vision, extremely high metabolic rates, nocturnal hibernation, high brain-to-body size ratio and a remarkable species-specific ...
    • Biogeographic analysis of the woody plants of the Southern Appalachians: Implications for the origins of a regional flora. 

      Manos, Paul S; Meireles, José Eduardo (Am J Bot, 2015-05)
      PREMISE OF THE STUDY: We investigated the origins of 252 Southern Appalachian woody species representing 158 clades to analyze larger patterns of biogeographic connectivity around the northern hemisphere. We tested biogeographic ...
    • Biogeography in deep time - What do phylogenetics, geology, and paleoclimate tell us about early platyrrhine evolution? 

      Kay, Richard Frederick (Mol Phylogenet Evol, 2015-01)
      Molecular data have converged on a consensus about the genus-level phylogeny of extant platyrrhine monkeys, but for most extinct taxa and certainly for those older than the Pleistocene we must rely upon morphological evidence ...
    • Brain evolution by brain pathway duplication. 

      Chakraborty, Mukta; Jarvis, Erich D (Philos Trans R Soc Lond B Biol Sci, 2015-12-19)
      Understanding the mechanisms of evolution of brain pathways for complex behaviours is still in its infancy. Making further advances requires a deeper understanding of brain homologies, novelties and analogies. It also requires ...
    • Cell type- and species-specific host responses to Toxoplasma gondii and its near relatives. 

      Wong, Zhee S; Borrelli, Sarah L Sokol; Coyne, Carolyn C; Boyle, Jon P (International journal for parasitology, 2020-05-11)
      Toxoplasma gondii is remarkably unique in its ability to successfully infect vertebrate hosts from multiple phyla and can successfully infect most cells within these organisms. The infection outcome in each of these species ...
    • Chimpanzees and bonobos exhibit divergent spatial memory development. 

      Rosati, Alexandra G; Hare, Brian (Dev Sci, 2012-11)
      Spatial cognition and memory are critical cognitive skills underlying foraging behaviors for all primates. While the emergence of these skills has been the focus of much research on human children, little is known about ...
