Regressive evolution of eyes in subterranean water beetles of arid-zone Australia: A comparative phylogenetic approach. Reduction or total loss of non-functional characters are common evolutionary phenomena, but little is known of the genetic basis of this regressive evolution. This project will use a phylogenetic framework to investigate the forces responsible for evolution of eyelessness in subterranean water beetles, by studying molecular genetic variation in three key eye developmental genes ....Regressive evolution of eyes in subterranean water beetles of arid-zone Australia: A comparative phylogenetic approach. Reduction or total loss of non-functional characters are common evolutionary phenomena, but little is known of the genetic basis of this regressive evolution. This project will use a phylogenetic framework to investigate the forces responsible for evolution of eyelessness in subterranean water beetles, by studying molecular genetic variation in three key eye developmental genes. The water beetles are explicitly suitable to address the questions due to their numerous independently evolved eyeless species and relatively old age of divergence from surface relatives. The research will provide a major new perspective on regressive evolution and the relationship between gene structure and function.Read moreRead less
Major Evolutionary Events in Reptiles (Including Birds). Evolutionary patterns among the major groups of reptiles (including birds) will be resolved using new information from multiple (>6) nuclear genes combined with existing phenotypic and (mainly mitochondrial) genetic traits. This will simultaneously resolve several high-profile questions, such as: the origin and affinities of turtles, snakes and flightless birds; and the prevalence of phenotypic convergence generated by paedomorphosis and ....Major Evolutionary Events in Reptiles (Including Birds). Evolutionary patterns among the major groups of reptiles (including birds) will be resolved using new information from multiple (>6) nuclear genes combined with existing phenotypic and (mainly mitochondrial) genetic traits. This will simultaneously resolve several high-profile questions, such as: the origin and affinities of turtles, snakes and flightless birds; and the prevalence of phenotypic convergence generated by paedomorphosis and fossoriality. The multiple genetic and phenotypic data sets will also reveal any broad links between genetic and phenotypic evolution (e.g. rate correlations), and the differing abilities of nuclear genes, mitochondrial genes, and phenotypic traits to track (and thus reflect) deep evolutionary branchings.Read moreRead less
