Quantitative traits and mode of speciation in Martinique anoles.
We investigate extensive quantitative trait variation (dewlap hue, colour pattern, dorsum hue, body proportions and scalation) in the Martinique anole across eight transects representing nascent parapatric ecological speciation, nascent allopatric speciation and allopatric divergence without sufficient genetic structure to suggest speciation. Quantitative trait divergence can be extremely large...
متن کاملPleiotropy, ‘‘sexy’’ traits, and speciation
The evolution of mating signals and preferences assists speciation by facilitating assortative mating within diverging lineages, thereby closing down conduits of gene flow between lineages. However, sexual communication traits are frequently subject to stabilizing selection, suggesting that new variants will be selected against, thereby discouraging their divergent evolution. Pleiotropic mutati...
متن کاملThe relative importance of ecology and geographic isolation for speciation in anoles.
The biogeographic patterns in sexually reproducing animals in island archipelagos may be interpreted as reflecting the importance of allopatric speciation. However, as the forms are allopatric, their reproductive isolation is largely untestable. A historical perspective integrating geology and molecular phylogeny reveals specific cases where ancient precursor islands coalesce, which allows the ...
متن کاملGenetic Tests for Ecological and Allopatric Speciation in Anoles on an Island Archipelago
From Darwin's study of the Galapagos and Wallace's study of Indonesia, islands have played an important role in evolutionary investigations, and radiations within archipelagos are readily interpreted as supporting the conventional view of allopatric speciation. Even during the ongoing paradigm shift towards other modes of speciation, island radiations, such as the Lesser Antillean anoles, are t...
متن کاملQuantitative Genetics and Quantitative Traits
Introduction In the chapter on Mendel and Morgan, we saw how the transmission of genes from one generation to another follows precise mathematical formula. The traits discussed in that chapter, however, were discrete traits—peas are either yellow or green, someone either has a disorder or does not have the disorder. But many behavioral traits are not like these clear-cut, have-it-or-don’t-have-...
