Speciation in birds: genes, geography, and sexual selection.
Molecular studies of speciation in birds over the last three decades have been dominated by a focus on the geography, ecology, and timing of speciation, a tradition traceable to Mayr's Systematics and the Origin of Species. However, in the recent years, interest in the behavioral and molecular mechanisms of speciation in birds has increased, building in part on the older traditions and observat...
متن کاملSelection on X-linked genes during speciation in the Drosophila athabasca complex.
We present the results of a restriction site survey of variation at five loci in Drosophila athabasca, complimenting a previous study of the period locus. There is considerably greater differentiation between the three semispecies of D. athabasca at the period locus and two other X-linked genes (no-on-transient-A and E74A) than at three autosomal genes (Xdh, Adh and RC98). Using a modification ...
متن کاملSexual selection and speciation.
The power of sexual selection to drive changes in mate recognition traits gives it the potential to be a potent force in speciation. Much of the evidence to support this possibility comes from comparative studies that examine differences in the number of species between clades that apparently differ in the intensity of sexual selection. We argue that more detailed studies are needed, examining ...
متن کاملNatural selection and speciation.
A paper by Korol et al. (1) in this issue demonstrates significant premating reproductive divergence between Drosophila melanogaster populations adapted to distinct, but closely adjacent, habitats in ‘‘Evolution Canyon’’ on Mt. Carmel, Israel. The authors suggest that reproductive isolation has evolved in situ as a result of adaptive divergence in response to the contrasting environments of nor...
