Egg retention and intrauterine embryonic development in Sceloporus aeneus (Reptilia: Phrynosomatidae): implications for the evolution of viviparity Retención de huevos y avance embrionario intrauterino en Sceloporus aeneus (Reptilia: Phrynosomatidae): implicaciones para la evolución de la viviparidad

Revista Mexicana de Biodiversidad, 2012
Egg retention (ER) and intrauterine embryonic development (IED) have been considered intermediate steps in the evolution from oviparity to viviparity. Sceloporus aeneus is an oviparous lizard that is closely related to the viviparous species (Sceloporus ...

Color vision evolution in egg-laying mammals: insights from visual photoreceptors and daily activities of Australian echidnas

Zoological Letters
Egg-laying mammals (monotremes) are considered “primitive” due to traits such as oviparity, cloaca, and incomplete homeothermy, all of which they share with reptiles.
