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 reproductive output in squamate reptiles. If females are “full” of eggs, what happens when viviparity evolves within a lineage? Eggs increase in volume and mass during development, primarily due to the… CONTINUE READING
