The evolution and development of complex molars as a key innovation in mammals have long been of interest yet remain poorly understood. With reference to century-old theories and modern findings, we ...

The radula is a distinctive, chitinous feeding apparatus found in most molluscs, and its specialised tooth structures play a crucial role in the efficient processing of food. In gastropods, the ...

Researchers demonstrated that declining Hedgehog signaling from Cilk1 loss produces stepwise changes in tooth formation ...

Researchers at the University of Zurich Center for Dental Medicine recently studied the Notch pathway’s role in the evolution of tooth morphology, with their results being published in Cellular and ...

The interaction between genetics and tissue environment shapes how individual teeth form in different regions of the jaw. While most experimental studies have focused on mandibular (lower jaw) teeth, ...

Result of principal component analysis (PCA) on tooth morphology in Baikal seals and its relative species. Horizontal axis represents principal component 1 and vertical axis represents principal ...

Sabre-toothed predators – best know from the infamous Smilodon – evolved multiple times across different mammal groups. A new study, published today in Current Biology reveals why: these teeth were ...

New research reveals how genes inherited from Neanderthals and critical developmental markers like PITX2 influence tooth size, shedding light on human evolution and genetic diversity. Study: PITX2 ...
