  • The evolution of different forms of sociality : behavioral mechanisms and eco-evolutionary feedback 

    Van Der Post, Daniel Job; Verbrugge, Rineke; Hemelrijk, Charlotte (2015-01-28) - Journal article
    Different forms of sociality have evolved via unique evolutionary trajectories. However, it remains unknown to what extent trajectories of social evolution depend on the specific characteristics of different species. Our ...
  • Evolution of divergent female mating preference in response to experimental sexual selection 

    Debelle, Allan; Ritchie, Michael G.; Snook, Rhonda R. (2014-09) - Journal article
    Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence ...

    Cognition presents evolutionary research with one of its greatest challenges. Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by ...
  • Evolution of signal multiplexing by 14-3-3-binding 2R-ohnologue protein families in the vertebrates 

    Tinti, Michele; Johnson, Catherine; Toth, Rachel; Ferrier, David Ellard Keith; MacKintosh, Carol (2012-07) - Journal article
    14-3-3 proteins regulate cellular responses to stimuli by docking onto pairs of phosphorylated residues on target proteins. The present study shows that the human 14-3-3-binding phosphoproteome is highly enriched in ...
  • The evolution of the cold interstellar medium in galaxies following a starburst 

    Rowlands, K.; Wild, V.; Nesvadba, N.; Sibthorpe, B.; Mortier, A.; Lehnert, M.; da Cunha, E. (2015-03-01) - Journal article
    We present the evolution of dust and molecular gas properties in a sample of 11 z ˜ 0.03 starburst to post-starburst (PSB) galaxies selected to span an age sequence from ongoing starburst to 1 Gyr after the starburst ended. ...
  • Evolution of the multifaceted eukaryotic akirin gene family 

    Macqueen, Daniel J.; Johnston, Ian A. (2009-02-06) - Journal article
    Background: Akirins are nuclear proteins that form part of an innate immune response pathway conserved in Drosophila and mice. This studies aim was to characterise the evolution of akirin gene structure and protein function ...
  • Evolution of the role of RA and FGF signals in the control of somitogenesis in chordates 

    Bertrand, Stéphanie; Aldea, Daniel; Oulion, Silvan; Subirana, Lucie; de Lera, Angel R.; Somorjai, Ildiko Maureen Lara; Escriva, Hector (2015-09-15) - Journal article
    During vertebrate development, the paraxial mesoderm becomes segmented, forming somites that will give rise to dermis, axial skeleton and skeletal muscles. Although recently challenged, the "clock and wavefront" model for ...
