Sexual selection accelerates signal evolution during speciation in birds
Sexual selection is proposed to be an important driver of diversification in animal systems, yet previous tests of this hypothesis have produced mixed results and the mechanisms involved remain unclear. Here, we use a novel phylogenetic approach to assess the influence of sexual selection on patterns of evolutionary change during 84 recent speciation events across 23 passerine bird families. We...
متن کاملSexual selection paves the road to sexual isolation during ecological speciation
Background: Divergent natural selection between ecologically different environments often drives speciation. An unanswered question concerns the importance of sexual selection in generating sexual isolation during this process. We illustrate that four distinct mechanisms can drive sexual isolation: (I) divergent sexual selection, (II) uniform sexual selection, (III) intrapopulation assortative ...
متن کاملGenetic Divergence, Reproductive Isolation, and Marine Speciation
In marine species, high dispersal is often associated with only mild genetic differentiation over large spatial scales. Despite this generalization, there are numerous reasons for the accumulation of genetic differences between large, semi-isolated marine populations. A suite of well-known evolutionary mechanisms can operate within and between populations to result in genetic divergence, and th...
متن کاملGenomic linkage of male song and female acoustic preference QTL underlying a rapid species radiation.
The genetic coupling hypothesis of signal-preference evolution, whereby the same genes control male signal and female preference for that signal, was first inspired by the evolution of cricket acoustic communication nearly 50 years ago. To examine this hypothesis, we compared the genomic location of quantitative trait loci (QTL) underlying male song and female acoustic preference variation in t...
متن کاملDimensionality of mate choice, sexual isolation, and speciation.
Multiple cues, across multiple sensory modalities, are involved in mate choice in a wide range of animal taxa. This multiplicity leads to the prediction that, in adaptive radiations, sexual isolation results from divergence in multiple dimensions. However, difficulties in directly measuring preferences and detecting multiple effects limit our ability to empirically assess the number of independ...
