Data from: Geographic and temporal dynamics of a global radiation and diversification in the killer whale
Global climate change during the Late Pleistocene periodically encroached and then released habitat during the glacial cycles, causing range expansions and contractions in some species. These dynamics have played a major role in geographic radiations, diversification and speciation. We investigate t...
