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.

The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

Teeth are maintained in two amphibian groups (caecilians and salamanders) but were lost in frogs over 20 times independently, a higher incidence of edentulism than any other major vertebrate group.

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.

A consistent pattern of consumption of Triticeae tribe grasses documented in the Danube Gorges of the Balkans since the Early Mesolithic might have facilitated a quick uptake of domesticated cereals due to a developed cultural taste and specific stone tool processing technology.

Flying squirrels may have originated earlier than previously thought and remained unchanged for almost 12 million years.

Ezh2 and Arid1a oppose each other to control expression of Cdkn2a to coordinate tooth furcation development and ultimately determine the number of roots in mouse molars.

The ancestor of all known jawed vertebrates possessed a maxilla and premaxilla and was similar in morphology to the 'maxillate placoderms' from China.

The nature and extent of developmental variation seen between mouse strains and genetically identical individuals explain why the first upper molar evolves along preferred path in murine rodents.

The inclusive, exclusive, and hierarchical atlas of NFATc1⁺/PDGFR-α⁺ cells in dental and periodontal mesenchyme is described.
