Congratulations to Emilie Richards (Chris Martin’s lab) for her publication in PLOS Genetics titled “Adaptive introgression from distant Caribbean islands contributed to the diversification of a microendemic adaptive radiation of trophic specialist pupfishes.” Emilie demonstrates that rare introgression of adaptive alleles linked to novel craniofacial phenotypes may be necessary for adaptive radiation in addition to the traditional paradigm of ecological opportunity. Intriguingly, narrowly endemic species are assembled from different pots of genetic variation over a very large range.
