It is concluded that measures of uncertainty are useful and should always be provided, despite simplistic assumptions about the probabilistic models that underlie them, and if uncertainty is too high, reconstruction should be abandoned. Expand
The role of phenotypic plasticity in driving genetic evolution
The role of phenotypic plasticity in stimulating evolution is assessed by considering two examples from birds: (i) the evolution of red and yellow plumage coloration due to carotenoid consumption; and (ii) the Evolution of foraging behaviours on islands. Expand
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
Two major hypotheses for the origin of the latitudinal diversity gradient are reviewed, including the time and area hypothesis and the diversification rate hypothesis, which hold that tropical regions diversify faster due to higher rates of speciation, or due to lower extinction rates. Expand
Population genomics of Bronze Age Eurasia
It is shown that the Bronze Age was a highly dynamic period involving large-scale population migrations and replacements, responsible for shaping major parts of present-day demographic structure in both Europe and Asia. Expand
Density-Dependent Cladogenesis in Birds
A meta-analysis of the distribution of speciation events through time for 45 clades of birds shows a model of density-dependent speciation in birds, whereby speciation slows as ecological opportunities and geographical space place limits on clade growth. Expand
Sexual selection and natural selection in bird speciation
It is concluded that perhaps the main role for sexual selection in speciation is in generating differences between populations in traits, and sexual selection is likely to have an important role in generating premating isolating mechanisms throughout an adaptive radiation. Expand
Speciation in a ring
This work reconstructs the pathway to speciation between two reproductively isolated forms of greenish warbler and shows how gradual divergence in a trait involved in mate choice leads to theformation of new species. Expand

It is argued that third variables are largely not controlled by the contrast methods, which are designed to estimate correlated evolution, and that assessing significance based on the species correlations can be justified, providing that attention is paid to the role of potentially confounding third traits.

Isolation and characterization of microsatellite loci in a Phylloscopus warbler
The research aims at investigating genetic structuring along an altitudinal gradient in its Himalayan breeding quarters and how this is related to morphological differentiation. Expand
