It is demonstrated that herbicide resistance encompasses contrasting genetic routes, with polygenic NTSR evolving largely through selection on standing variation, offering broader insights into the evolutionary dynamics of rapid polygenic adaptation under novel anthropogenic selection.
Hybridization may have multiple impacts on speciation and adaptation. Yet the evidence of adaptive introgression events that have historically occurred between nonradiating or established species is still lacking. The oakleaf butterflies in the genus Kallima include multiple sympatric and incipient species with a kno...

Demographic processes such as colonization to new environments and gene flow fundamentally shape the genomic landscape, either facilitating or constraining the efficiency of selection by altering the balance between genetic diversity and adaptive responses. Although theoretical predictions suggest that the efficacy of...

The results demonstrate that genomic architecture actively dictates evolutionary speed, suggesting that certain lineages boosted by structural variants may bypass the typical constraints of purifying selection to rapidly exploit vacant ecological opportunities.

The observations support the prediction that genotype‐environment association will be strongest under simple genetic architecture, although, even then, analysis in native populations may be confounded by population structure.

Climate change is increasing drought and heat stress in European forests, raising concerns about the capacity of long-lived tree species to respond to rapidly changing environmental conditions. While local adaptation has been documented in many forest trees, it remains unclear whether newly established seedlings, which...

Overall, these findings suggest the Malawi radiation formed through repeated intermingling of diverse cichlid lineages and that Malawi genomes are comprised of a complex mosaic of ancestries varying among species and individuals, and support the growing recognition that gene flow is an important driver of biodiversity.
