- Akaike information criterion (AIC) values for the four hypotheses tested in ouch. Based on data from the top 9 PCs representing 95.2% of variation in the sample. BM, Brownian motion model; One regime, single optimum for all Carnivora; Terrestrial-aquatic, one regime for terrestrial carnivorans, another for pinnipeds plus the otter; Pinniped radiation, one regime for fissipeds, another for pinnipeds. Bold shows best AIC values for the BM hypothesis in all cases.
