Population genomics finds veritas in the demographic history of vino

One of the more, hah, fruitful applications of genomic data has been in crop and livestock improvement. Biologists know that domesticating plants and animals for human use has involved powerful artificial selection — usually inadvertent at first, then intensive and … Continue reading

Speciation reshapes the ways genetic diversity is distributed in the genome — it’s been said that the establishment of reproductive isolation is essentially the evolution of genome-wide linkage disequilibrium. The “genomic islands of speciation” model of ecological isolation imagines genome-wide … Continue reading
