Gene loss, adaptive evolution and the co-evolution of plumage coloration genes with opsins in birds.
(BMC Genomics, 2015-10-06)
BACKGROUND: The wide range of complex photic systems observed in birds exemplifies one of their key evolutionary adaptions, a well-developed visual system. However, genomic approaches have yet to be used to disentangle the ...
The Origin and Diversification of Birds.
(Curr Biol, 2015-10-05)
Birds are one of the most recognizable and diverse groups of modern vertebrates. Over the past two decades, a wealth of new fossil discoveries and phylogenetic and macroevolutionary studies has transformed our understanding ...
Brain evolution by brain pathway duplication.
(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 ...
A refined model of the genomic basis for phenotypic variation in vertebrate hemostasis.
(BMC Evol Biol, 2015-06-30)
BACKGROUND: Hemostasis is a defense mechanism that enhances an organism's survival by minimizing blood loss upon vascular injury. In vertebrates, hemostasis has been evolving with the cardio-vascular and hemodynamic systems ...
Human-chimpanzee differences in a FZD8 enhancer alter cell-cycle dynamics in the developing neocortex.
(Curr Biol, 2015-03-16)
The human neocortex differs from that of other great apes in several notable regards, including altered cell cycle, prolonged corticogenesis, and increased size [1-5]. Although these evolutionary changes most likely contributed ...
