Heat Selection May Help Species Spread Heat Tolerance Genes

New research published in PLOS Biology examines whether introgression—the movement of genes between species—can spread beneficial alleles as climate warming intensifies. The study finds that strong heat selection promotes introgression and heat tolerance even in the presence of genomic barriers to gene flow, suggesting adaptive genes may cross species boundaries under climate stress.
Why now: A newly published PLOS Biology study offers evidence that adaptive heat-tolerance genes can overcome genomic barriers, a finding relevant to how species adapt to warming.
