Aim
The evolution of viviparity in squamate reptiles has attracted considerable scientific attention since the beginning of last century. The cold‐climate hypothesis posits that cold regions favor viviparity (and therefore the incidence of viviparous squamates is increased in these regions) because viviparous females can use thermoregulatory behavior to shorten embryonic developmental time and to...
