A specialized conduction pathway for the electrical impulse in the heart, previously thought to be associated with the endothermic mammals and birds only, is also present in the ectothermic crocodiles.

Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.

Why is the alligator heart so similar to the hearts of birds and mammals?

More integrated brains in crown birds evolved through a mosaic assembly of new evolutionary and developmental dynamics across neuroanatomical regions that occurred along the dinosaur-bird transition.

Elephants escaped enhanced cancer susceptibility by evolving more master tumor suppressor genes.

Amphibians, reptiles, and birds engage pyroptosis using caspase-1 and GSDMA, filling an evolutionary gap in which caspase-1 cleaves GSDME in fish and GSDMD in mammals.

Facultative parthenogenesis in whiptail lizards produces genome-wide homozygosity in offspring.

Whole-genome in silico screening for stop codon contexts that produce elevated translational readthrough and peroxisome targeting reveals that in mammals, the amount of lactate dehydrogenase in the peroxisome is controlled by translational readthrough.

The tooth replacement pattern of early-diverging ceratopsians helps to understand the origin of the specialized dental system of ceratopsids and provides new insights to feeding strategy transition.
