Repeated evolution of exaggerated dewlaps and other throat morphology in lizards.

T J Ord et al.

Journal of evolutionary biology, 28(11), 1948-1964 (2015-08-04)

The existence of elaborate ornamental structures in males is often assumed to reflect the outcome of female mate choice for showy males. However, female mate choice appears weak in many iguanian lizards, but males still exhibit an array of ornament-like

Which came first: The lizard or the egg? Robustness in phylogenetic reconstruction of ancestral states.

April M Wright et al.

Journal of experimental zoology. Part B, Molecular and developmental evolution, 324(6), 504-516 (2015-08-01)

Changes in parity mode between egg-laying (oviparity) and live-bearing (viviparity) have occurred repeatedly throughout vertebrate evolution. Oviparity is the ancestral amniote state, and viviparity has evolved many times independently within amniotes (especially in lizards and snakes), with possibly a few
