Differing effects of size and lifestyle on bone structure in mammals

摘要

Lifestyle transitions among mammals. Colours correspond to the specialised lifestyles, i.e. aerial, aquatic, and subterranean; black corresponds to ‘non-specialised’ lifestyles. States at the nodes are reconstructed with stochastic character mapping. Lifestyle transitions were emphasised with larger nodes for clades and coloured branches for single taxa. Each silhouette represents an independent acquisition of one of the three specialised lifestyles. Abbreviations: Anom., Anomaluromorpha; Lag., Lagomorpha; Mo., Monotremata; Xe, Xenarthra
