The majority of creationists freely admit the existence of biological variation, adaptation and speciation. But, how do they reconcile this with their rejection of evolution? A former young-Earth ...

We relate variations in speciation rates to six key patterns of biodiversity worldwide, including the species–area relationship, latitudinal gradients in species and genetic diversity ...

III. Islands as "natural laboratories" for exploring speciation We all know how much of an influence the juxtaposition of variation and similarity among islands in the Galapagos archipelago played in ...

Often this type of speciation occurs in three steps ... so that even if some variation occurs, it is limited by this "gene flow." But gene flow is interrupted if the population becomes divided ...

Habitat variation may also contribute to local adaptation ... which is a necessary precursor to speciation. Future studies that incorporate ecological, behavioral, and genetic data hold great ...

(sympatric speciation.) The achievement an answer would be magnificent, if niche variation between the 2 NE Atlantic populations could be observed. This variation could be the raw material for their ...

Darwin's finches, inhabiting the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and ... a gene that explains variation in beak shape within and ...

among all individual birds suggesting that most retrovirus-host interactions pre-date host speciation. They also found considerable ERV variation across different populations of Darwin's finches ...

However, geographically proximate marine and freshwater ecotypes displayed significant genetic variation in 81 different genome loci – corresponding to natural selection, which favours certain ...

We are now conducting microsatellite analysis of these populations, and examining variation in opsin genes as candidates for driving differentiation and speciation.
