Frontiers in Zoology, 2021 Parity mode (oviparity/viviparity) importantly affects the ecology, morphology, physiology, biogeography and evolution of organisms. The main hypotheses explaining the evolution and maintenance of viviparity are based on bioclimatic predictions and also ...

Common lizards break Dollo’s law of irreversibility: genome-wide phylogenomics support a single origin of viviparity and re-evolution of oviparity [PDF]
, 2018 Dollo’s law of irreversibility states that once a complex trait has been lost in evolution, it cannot be regained. It is thought that complex epistatic interactions and developmental constraints impede the re-emergence of such a trait.

Progressive Exaptation of Endogenous Retroviruses in Placental Evolution in Cattle
Biomolecules, 2023 Viviparity is made possible by the placenta, a structure acquired relatively recently in the evolutionary history of eutherian mammals. Compared to oviparity, it increases the survival rate of the fetus, owing to the eutherian placenta. Questions such as

Características histológicas del útero de Sympterygia acuta (Garman, 1877) y Sympterygia bonapartii (Müller & Henle, 1841) (Chondrichthyes; Rajidae) [PDF]
, 2013 Los condrictios constituyen un clado sumamente conservado y vulnerable a la explotación, que ha cobrado una importancia creciente en los últimos años. Sin embargo, existe poca información sobre los aspectos morfológicos relacionados con la reproducción ...

Bacterial community dynamics during embryonic development of the little skate (Leucoraja erinacea)
Animal Microbiome, 2021 Background Microbial transmission from parent to offspring is hypothesized to be widespread in vertebrates. However, evidence for this is limited as many evolutionarily important clades remain unexamined.

Growth and reproduction in captivity unveils remarkable life-history plasticity in the smallnose fanskate, Sympterygia bonapartii (Chondrichthyes: Rajiformes) [PDF]
, 2018 Analizamos el crecimiento y la reproducción de ejemplares de raya marmorada, Sympterygia bonapartii nacidas en cautiverio. Se obtuvieron ovicápsulas a partir de la oviposición de dos hembras capturadas en la naturaleza y mantenidas en el Acuario Temaikèn.
