Some snakes lay eggs, while others give birth to living young. The oviparous condition is the primitive one; but viviparity developed early in the history of snakes, and some of the most primitive extant ophidians are live-bearers. Among United States snakes viviparity follows phylogenetic lines; the only live-bearing snakes of this country are boas, pit vipers, and a closely related group of genera belonging to the harmless snake family Colubridae. Even when the geographic view is expanded to… Expand
REPTILIAN VIVIPARITY AND DOLLO'S LAW
TLDR
Using available data on reproductive modes and phylogenetic relationships within reptiles, the numbers and directions of evolutionary transitions between oviparity and viviparity are measured. Expand
Lerista bougainvillii, a case study for the evolution of viviparity in reptiles
TLDR
Comparison with 31 sympatric scincid species showed that L. bougainvillii is not atypical for most of the traits it displays, and climatic unpredictability is lower for viviparous animals, in contradiction to published speculations. Expand
Phylogenetic position of a bizarre lizard Harpesaurus implies the co-evolution between arboreality, locomotion, and reproductive mode in Draconinae (Squamata: Agamidae)
TLDR
It is suggested that the use of arboreal habitats and slow locomotion facilitated the evolution of viviparity in these tropical/subtropical lizards, and it is proposed that such species are relatively insusceptible to the concomitant cost of v Viviparity: reduced locomotive ability and increased risk of predation during pregnancy.

EVOLUTION OF VIVIPARITY IN THE LIZARD GENUS SCELOPORUS
TLDR
Within oviparous species of Sceloporus, animals exhibiting egg retention have a selective advantage over conspecifics in the cold environments of high elevation or latitude and viviparity evolves as an irreversible trait. Expand
THE EVOLUTION OF OVIPARITY WITH EGG GUARDING AND VIVIPARITY IN LIZARDS AND SNAKES: A PHYLOGENETIC ANALYSIS
This paper investigates the evolution of viviparity and of egg guarding in lizards and snakes in which three modes of reproduction can be described: oviparity without egg guarding, oviparity with eggExpand
Ovoviviparity and viviparity in the Diptera
TLDR
Viviparity in Diptera provides a fascinating example of multiple parallel evolution, and a fertile field for future research, as well as potential advantages of shorter larval life and better access to breeding substrates. Expand

TLDR
Future studies and analyses should abandon assumptions of universal physiological mechanisms and a single historical sequence, in favor of the documentation of diversity in phylogenetic and quantitative terms. Expand
The evolution of viviparity: ecological correlates of reproductive mode within a genus of Australian snakes (Pseudechis: Elapidae)
TLDR
The "cold climate" hypothesis is the only one which successfully predicts ecological correlates of reproductive mode in Pseudechis, and strongly falsify several hypotheses on morphological and ecological consequences of the evolution of viviparity. Expand
The geography of snake reproductive mode: a global analysis of the evolution of snake viviparity
TLDR
It is concluded that viviparity is adaptive in cold climates, but not necessarily in unpredictable/seasonal climates. Expand
Amniote Perspectives on the Evolutionary Origins of Viviparity and Placentation
Phylogenetic analyses of reproductive patterns have clarified several aspects of the evolution of viviparity in reptiles and mammals, and offer useful comparisons to that pattern in fishes. InExpand

TLDR
It is suggested that in reptiles with and obvious reduction in the yolk-content of their eggs at the time of ovulation, and its invaribale accompaniment by a speciallized folded glandular area of allanto-placentation, theYolk-sac placenta would gradually lose significance as a water absorbing organ, but the most primitive expression of viviparity among repitles.

The ancestors of snakes, irrespective of their habits, were closely related to the platynotid lizards, and the respective merits of these assumptions must mainly be assessed on evidence obtained from study of living forms. Expand
