AbstractLocally adapted traits can exhibit a wide range of genetic architectures, from pronounced divergence at a few loci to small allele frequency shifts at many loci. The type of architecture that evolves depends strongly on migration rate, as weakly selected loci experience swamping and do not make stable contributions to divergence.

AbstractGlobal adaptation occurs when all populations of a species undergo selection toward a common optimum. This can occur by a hard selective sweep with the emergence of a new globally advantageous allele that spreads throughout a species' natural range until reaching fixation. This evolutionary process leaves a temporary trace in the region affected, which is detectable using population genomic methods.
