Using CAT scans, Idaho State University researchers have made 3D virtual reconstructions of the jaws of the ancient spiral-toothed fish Helicoprion.
A single mutation around 30,000 years ago appears to be responsible for several traits common in East Asian peoples, from thicker hair to denser sweat glands.
A new fossil discovery has shown that some early birds evolved teeth adapted for specialized diets.
Our early ancestors in Central Africa, between three million and 3.5 million years ago, munched mainly on tropical grasses and sedges - a much earlier change in diet than previously believed.
Duck-billed dinosaurs had amazingly complex teeth - much more so than those of cows, horses, and other modern grazers - allowing them to chew tough and abrasive plants with great efficiency.
Just like us, Neanderthals were mostly right-handed, new research has confirmed - possibly indicating a capacity for language.
Bits of food stuck between the teeth of a two-million-year-old South African hominid show that, unlike almost all other known human ancestors, it ate tree bark and other hard foods.
Scientists from Japan recently published a paper that details how they successfully grew new teeth from the stem cells of mice.
Tools that sharpen themselves every time they're used could soon be available, following a discovery about the way sea urchins keep their teeth sharp.
