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 ...

Researchers discovered how genetic switches shaped human brain evolution by fine-tuning shared gene expression.

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.

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the ...

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 ...

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 ...

The adaptive evolution of giraffes is a remarkable demonstration ... When we started getting results from our analyses of gene flow between different giraffe lineages, we had to check twice.

Urban environments have the potential to influence the evolution of species in numerous ways. Some of these effects are nonadaptive, and are largely driven by changes in gene flow between populations.
