Reasons for divergence within the animal kingdom is heavily debated across many orders. Macroevolution in Cetacea has been attributed to a variety of ecological and environmental dynamics which set the stage for the success of modern whales. In this meta-analysis, we investigate the magnitude of support for two current competing hypotheses explaining the divergence of Neoceti from archaic whales (Archaeoceti) …show more content…
Fitzgerald (2006) and Demere et al. (2008) provide evidence that the initial mysticete radiation did not coincide with the appearance of traits associated with bulk filter-feeding. Other studies suggest that previous timeframe estimates are incorrect, and that either the establishment of the Antarctic Circumpolar Current (Pfuhl and Cave 2005) or the radiation of the Mysticeti (Geisler et al. 2011) occurred much later than previously …show more content…
