A large comparative study of primate teeth shows that grooves once linked to ancient human tooth-picking can form naturally, while some common modern dental problems appear uniquely human.

Researchers have investigated the importance of the Notch pathway for the evolution of tooth morphology. Mutations in this signalling pathway can lead to defective structures in tooth enamel. Studies ...

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, ...

The enamel that forms the outer layer of our teeth might seem like an unlikely place to find clues about evolution. But it tells us more than you’d think about the relationships between our fossil ...

The cichlid fish of Africa's Great Lakes have formed new species more rapidly than any other group of vertebrates. A new study shows that the ease with which these fish can develop a biological ...

Studies of mammalian evolution often rely on the analyses of teeth, which are the best-preserved parts of fossilized skeletons. Tooth morphology and the composition of enamel – the most mineralized ...
