Comparative genomics reveals divergent thermal selection in warm‐ and cold‐tolerant marine mussels

Investigating the history of natural selection among closely related species can elucidate how genomes diverge in response to disparate environmental pressures. Molecular evolutionary approaches can be integrated with knowledge of gene functions to examine how evolutionary divergence may affect ecologically relevant traits such as temperature tolerance and species distribution limits. Here, we integrate transcriptome‐wide analyses of molecular...
