Table 4 Ancestral state reconstruction of adult female body mass (kg) based on a dataset of 1,679 eutherian mammal species means, under Brownian Motion (BM; maximum likelihood), Ornstein-Uhlenbeck (OU; maximum likelihood), Early Burst (EB; maximum likelihood), Eastman et al 's (2011) heterogenous multi-rate (maximum posterior probability) and stable (maximum posterior probability) models
