## Abstract Following their origin during the early Cretaceous, the lizards radiated early into a number of families. This radiation was accompanied by a diversification in the structure of the inner ear. The morphology of the auditory basilar papilla is family‐specific, with large variations in a

In reptiles, the evolutionary transition from egg-laying to livebearing is thought to involve a gradual increase in the duration of egg retention, with progressively more development occurring prior to oviposition, and culminating in the birth of fully developed offspring. However, prolonging the re

A few species of squamate reptiles contain both oviparous (egg-laying) and viviparous (live-bearing) populations, and thus offer exceptional opportunities to test adaptationist hypotheses on the determinants of reproductive output. We focus on the hypothesis that maternal body-volume constrains repr
