Squamate reptiles\, as one of the most diverse groups of tetrapods\, represent an ideal system for studying diversification dynamics. Using geck os and snakes\, we tested the relationships between speciation\, phenotypic diversification\, and ecological opportunity. In some geckos\, it appears that speciation and trait diversification are uncoupled\, which contradicts the expectations of adaptive radiation theory. Rather\, speciation and tra it diversification seem to respond to ecological opportunity independently and trait evolution is largely idiosyncratic amongst clades. In caenophidia n snakes we find strong signatures of ‘deterministic’ evolution at the oste ological level with ecomorphs being replicated across highly divergent taxa . Conversely\, there appears to some level of many‐to‐one mapping for super ficially similar taxa where\ndifferent changes between elements lead to fun ctionally similar modules.
