Did adaptive radiations (sensu Simpson) shape reptile evolution???? Using a total-evidence dating approach, Postdoc fellow Tiago Simões uncovers a complex evolutionary scenario in which different parts of the diapsid and lepidosaur tree of life are often better explained by alternative megaevolutionary models - contradicting decades old dogma. The findings further suggest that phenotypic novelties converging on similar functions (e.g. snake-like body plan) evolved at very distinct rates of evolution. And, that snake have the highest rate of evolution compared to all reptiles!
