Data from: Independent evolution of baleen whale gigantism linked to Plio-Pleistocene ocean dynamics
Vertebrates have evolved to gigantic sizes repeatedly over the past 250 Myr, reaching their extreme in today's baleen whales (Mysticeti). Hypotheses for the evolution of exceptionally large size in mysticetes range from niche partitioning to predator avoidance, but there has been no quantitativ...
