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
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 bicanthalis). The present study addresses the...
