      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, GH; Vega, IE; Wahl, KJ; Orihuela, B; Beyley, V; Rodriguez, EN; Everett, RK; ... (9 authors) (J Exp Biol, 2009-11)
      Enzymes and biochemical mechanisms essential to survival are under extreme selective pressure and are highly conserved through evolutionary time. We applied this evolutionary concept to barnacle cement polymerization, a ...
    • Behaviourally driven gene expression reveals song nuclei in hummingbird brain. 

      da Silva, ML; Jarvis, Erich David; Mello, CV; Ribeiro, S; Ventura, D; Vielliard, J (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, JE (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, M; Jarvis, Erich David (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 ...
    • Chimpanzees and bonobos exhibit divergent spatial memory development. 

      Hare, Brian; Rosati, Alexandra G (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 ...
    • Chromosomal organization of adrenergic receptor genes. 

      Caron, MG; Cotecchia, S; Francke, U; Frielle, T; Lefkowitz, Robert J; Xue, FY; Yang-Feng, TL; ... (8 authors) (Proc Natl Acad Sci U S A, 1990-02)
      The adrenergic receptors (ARs) (subtypes alpha 1, alpha 2, beta 1, and beta 2) are a prototypic family of guanine nucleotide binding regulatory protein-coupled receptors that mediate the physiological effects of the hormone ...
    • Comparative genomics reveals insights into avian genome evolution and adaptation. 

      Alfaro-Núñez, A; Alström, P; An, N; Antunes, A; Avian Genome Consortium; Bertelsen, MF; Borges, R; ... (106 authors) (Science, 2014-12-12)
      Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. ...
    • Complex evolutionary trajectories of sex chromosomes across bird taxa. 

      An, N; Bachtrog, D; Gilbert, M Thomas P; Huang, Q; Jarvis, Erich David; Zhang, G; Zhang, J; ... (8 authors) (Science, 2014-12-12)
      Sex-specific chromosomes, like the W of most female birds and the Y of male mammals, usually have lost most genes owing to a lack of recombination. We analyze newly available genomes of 17 bird species representing the avian ...
