Phylogenies, the Comparative Method, and the Conflation of Tempo and Mode

Antigoni Kaliontzopoulou and Dean C. Adams. Systematic Biology, 2015. The comparison of mathematical models that represent alternative hypotheses about the tempo and mode of evolutionary change is a common approach for assessing the evolutionary processes underlying phenotypic diversification. However, because model parameters are estimated simultaneously, they are inextricably linked, such that changes in tempo, the pace of evolution, and mode, the manner in which evolution occurs, may be difficult to assess separately.
