A team of scientists from Princeton University and Uppsala University detail their findings of how gene flow between two species of Darwin’s finches has affected their beak morphology in the May 4 ...

Songbirds who make the arduous flight from their nesting sites in northern boreal forests to warm, southern climates in the ...

In this scenario, the deleterious allele will remain at an intermediate equilibrium frequency that reflects the balance between gene flow and natural selection. The common conception of evolution ...

Giraffes are a beautiful and powerful example of what adaptive evolution can achieve ... we started getting results from our analyses of gene flow between different giraffe lineages, we had ...

As is often the case in evolution, the rules of speciation are ... What keeps a species coherent over time? "Gene flow" between the different populations of a species is one main explanation.

The team discovered a gene flow event in this species of apes ... In both species, their DNA was mixed during evolution by mating with individuals from other groups which are already extinct ...

Under normal conditions, genes in a given population are exchanged through breeding, so that even if some variation occurs, it is limited by this "gene flow." But gene flow is interrupted if the ...

One consequence of large-scale migrations is what biologists call gene flow, a type of evolution caused by the blending of genes between populations. When people from different populations mate ...

A team of scientists now reports how gene flow between two species of ... The study is published today in Nature Ecology and Evolution. Darwin's finches on the Galápagos Islands are an example ...
