Reanalysis suggests that genomic islands of speciation are due to reduced diversity, not reduced gene flow

TE Cruickshank, MW Hahn - Molecular ecology, 2014‏ - Wiley Online Library
The metaphor of 'genomic islands of speciation'was first used to describe heterogeneous
differentiation among loci between the genomes of closely related species. The biological …

Adaptation from standing genetic variation

RDH Barrett, D Schluter - Trends in ecology & evolution, 2008‏ - cell.com
Populations adapt to novel environments in two distinct ways: selection on pre-existing
genetic variation and selection on new mutations. These alternative sources of beneficial …

Selective sweeps

W Stephan - Genetics, 2019‏ - academic.oup.com
For almost 20 years, many inference methods have been developed to detect selective
sweeps and localize the targets of directional selection in the genome. These methods are …

Hitchhiking under positive Darwinian selection

JC Fay, CI Wu - Genetics, 2000‏ - academic.oup.com
Positive selection can be inferred from its effect on linked neutral variation. In the restrictive
case when there is no recombination, all linked variation is removed. If recombination is …

Molecular signatures of natural selection

R Nielsen - Annu. Rev. Genet., 2005‏ - annualreviews.org
There is an increasing interest in detecting genes, or genomic regions, that have been
targeted by natural selection. The interest stems from a basic desire to learn more about …

Detecting loci under selection in a hierarchically structured population

L Excoffier, T Hofer, M Foll - Heredity, 2009‏ - nature.com
Patterns of genetic diversity between populations are often used to detect loci under
selection in genome scans. Indeed, loci involved in local adaptations should show high F ST …

Interrogating a high-density SNP map for signatures of natural selection

JM Akey, G Zhang, K Zhang, L **… - Genome research, 2002‏ - genome.cshlp.org
Identifying genomic regions that have been targets of natural selection remains one of the
most important and challenging areas of research in genetics. To this end, we report an …

The coupling hypothesis: why genome scans may fail to map local adaptation genes

N Bierne, J Welch, E Loire, F Bonhomme… - Molecular …, 2011‏ - Wiley Online Library
Genomic scans of multiple populations often reveal marker loci with greatly increased
differentiation between populations. Often this differentiation coincides in space with …

Signals of recent positive selection in a worldwide sample of human populations

JK Pickrell, G Coop, J Novembre, S Kudaravalli… - Genome …, 2009‏ - genome.cshlp.org
Genome-wide scans for recent positive selection in humans have yielded insight into the
mechanisms underlying the extensive phenotypic diversity in our species, but have focused …

Recombination rate variation and speciation: theoretical predictions and empirical results from rabbits and mice

MW Nachman, BA Payseur - … Transactions of the Royal …, 2012‏ - royalsocietypublishing.org
Recently diverged taxa may continue to exchange genes. A number of models of speciation
with gene flow propose that the frequency of gene exchange will be lower in genomic …
