Genome-wide demographic analyses of balaenid whales revealed complex history of gene flow associated with past climate oscillation
The balaenid whale, comprising three species of right whales and the bowhead whale, represents an ancient and highly endangered lineage of marine mammals. To unravel the evolutionary history of balaenid whales with respect to gene flow, a comprehensive analysis based on whole-genome data was conduct...
