Different diversification scenarios have been proposed to explain the
origin of extant biodiversity. However, most existing meta-analyses of
time-calibrated phylogenies rely on approaches that do not quantitatively
test alternative diversification processes. Here, I highlight the
shortcomings of using species divergence ranks, which is a method widely
used in meta-analyses. Divergence ranks consist of categorizing
cladogenetic events to certain periods of time, typically to either
Pleistocene or to pre-Pleistocene ages. This approach has been claimed to
shed light on the origin of most extant species and the timing and
dynamics of diversification in any biogeographical region. However,
interpretations drawn from such method often confound two fundamental
questions in macroevolutionary studies, tempo (timing of evolutionary rate
shifts) and mode (“how” and “why” of speciation). By using simulated
phylogenies under four diversification scenarios, constant-rate,
diversity-dependence, high extinction, and high speciation rates in the
Pleistocene, I showed that interpretations based on species divergence
ranks might have been seriously misleading. Future meta-analyses of dated
phylogenies need to be aware of the impacts of incomplete taxonomic
sampling, tree topology, and divergence time uncertainties, as well as
they might be benefited by including quantitative tests of alternative
diversification models that acknowledge extinction and diversity
dependence.
