Fig. 2From: Insights from macroevolutionary modelling and ancestral state reconstruction into the radiation and historical dietary ecology of Lemuriformes (Primates, Mammalia)Mean rate evolution of dental adaptations for folivory at each time interval across the tree of Lemuriformes. Solid line indicates the mean rates at each bin of one-million-year duration. Dotted line with grey ribbon indicates LOWESS smoothed trend in the empirical data. The ~ 10 Ma before present shows a uniformly high mean rate of evolution, likely reflecting a “Sadler effect” of apparently rapid evolution in extant branches [47, 83]Back to article page
