Genetic polymorphism varies among species and within genomes, and has important
implications for the evolution and conservation of species. The determinants of this variation …

Speciation is often thought of as a slow process due to the waiting times for mutations that
cause incompatibilities, and permit ecological differentiation or assortative mating. Cases of …

Speciation results from the progressive accumulation of mutations that decrease the
probability of mating between parental populations or reduce the fitness of hybrids—the so …

Although some lineages of animals and plants have made impressive adaptive radiations
when provided with ecological opportunity, the propensities to radiate vary profoundly …

Comparative population genomics is an ascendant field using genomic comparisons
between species to draw inferences about forces regulating genetic variation. Comparative …

Understanding the processes shaping population structure and reproductive isolation of
marine organisms can improve their management and conservation. Using genomic …

A thorough reconstruction of historical processes is essential for a comprehensive
understanding of the mechanisms shaping patterns of genetic diversity. Indeed, past and …

Chromosomal rearrangements (eg, inversions, fusions, and translocations) have long been
associated with environmental variation in wild populations. New genomic tools provide the …

Across several animal taxa, the evolution of sociality involves a suite of characteristics, a
“social syndrome,” that includes cooperative breeding, reproductive skew, primary female …

HIV recombinants increase worldwide and invade geographical regions where pure
subtypes were previously predominant. This trend is expected to continue in the future, as …
