    MacQueen, Daniel John; Garcia de la Serrana Castillo, Daniel; Johnston, Ian Alistair (2013-05) - Journal article
    Whole genome duplication (WGD) was experienced twice by the vertebrate ancestor (2 rounds; 2R), again by the teleost fish ancestor (3R) and most recently in certain teleost lineages (4R). Consequently, vertebrate gene ...
  • The evolution of behaviour : a genetic approach 

    Parker, Darren J. (University of St Andrews, 2015-06-24) - Thesis
    In this thesis I investigated the genetic basis of several behaviours to answer questions surrounding the evolution and mechanistic basis of behaviour. Firstly, I took a single-gene approach to investigate the influence ...
  • The evolution of cerebellum structure correlates with nest complexity 

    Hall, Zachary Jonas; Street, Sally; Healy, Susan Denise (2013-12-04) - Journal article
    Across the brains of different bird species, the cerebellum varies greatly in the amount of surface folding (foliation). The degree of cerebellar foliation is thought to correlate positively with the processing capacity ...
  • 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 ...
  • Evolution of field line helicity during magnetic reconnection 

    Russell, A. J. B.; Yeates, A. R.; Hornig, G.; Wilmot-Smith, A. L. (2015-03) - Journal article
    We investigate the evolution of field line helicity for magnetic fields that connect two boundaries without null points, with emphasis on localized finite-B magnetic reconnection. Total ( relative) magnetic helicity is ...
  • Evolution of Helping and Harming in Viscous Populations When Group Size Varies 

    Rodrigues, Antonio M. M.; Gardner, Andy (2013) - Journal article
    Recent years have seen huge interest in understanding how demographic factors mediate the evolution of social behavior in viscous populations. Here we study the impact of variation in group size on the evolution of helping ...
  • The evolution of hermaphroditism by an infectious male-derived cell lineage : an inclusive-fitness analysis 

    Gardner, Andy; Ross, Laura (2011-08) - Journal article
    There has been much recent interest in the role for genetic conflicts to drive the evolution of genetic systems. Here we consider the evolution of hermaphroditism in the scale insect tribe Iceryini and the suggestion that ...
  • Evolution of homeobox gene clusters in animals : the Giga-cluster and primary versus secondary clustering 

    Ferrier, David Ellard Keith (2016-04-14) - Journal item
    The Hox gene cluster has been a major focus in evolutionary developmental biology. This is because of its key role in patterning animal development and widespread examples of changes in Hox genes being linked to the evolution ...
  • The evolution of novelty in conserved genes; evidence of positive selection in the Drosophila fruitless gene is localised to alternatively spliced exons 

    Parker, D. J.; Gardiner, A.; Neville, M. C.; Ritchie, M. G.; Goodwin, S. F. (2014-03) - Journal article
    There has been much debate concerning whether cis-regulatory or coding changes are more likely to produce evolutionary innovation or adaptation in gene function, but an additional complication is that some genes can ...
