Universal Grammar versus language diversity

The target article by Evans and Levinson (E&L) concludes that there is little, if any, empirical evidence corresponding to ‘immutable’ principles of Universal Grammar. It would be surprising indeed if Universal Grammar failed to leave its imprint on languages around the globe, but it is a misunderstanding of the theory to limit the search for linguistic universals to counting up construction-types across languages, as E&L do in the target article. Here is an instructive quote from Chomsky (1965:6).
