Viviparity and Temperature-Dependent Sex Determination
Sexual Development, 2009Although temperature-dependent sex determination (TSD) has been a ‘hot topic’ for well over 30 years, the discovery of TSD in viviparous taxa is recent. Viviparity and TSD was regarded unlikely on theoretical grounds as viviparity allows for high stable developmental temperatures through maternal basking.

In vertebrates, there are three principal modes of nutrition for developing embryos: (1) the laying down of food stores, synthesized in the liver, in the oocyte (vitellogenesis) (this is the most common mode in nonmammalian species); (2) the direct provision of nutrients to the developing young through the intermediary of the uterine wall by either ...

VIVIPARITY AND AVIAN REPRODUCTION
Ibis, 1962SUMMARYA number of theories have been proposed to explain the absence of viviparity in birds, based upon considerations of weight and hormonal control in reproduction. It is here suggested that viviparity has not developed in birds owing to the unusual pattern of ovulation which they possess, and which would lead to a graduated series of developing ...

The many problems we face in our efforts to maintain the mammalian fetus in vitro justify a brief scrutiny of the special niche normally occupied by the mammalian fetus, and some consideration of its principal features. Such a survey reasonably begins in the realm of phytogeny, with the evolutionary aspects of viviparity, and the developmental problems
