[Evolution of teeth].
True teeth developed approximately 230 million years ago. Mammals have an accurate dental occlusion, whereby the renewal of teeth has reduced to two sets of teeth. Since the shape of teeth does not change after eruption, they form a good subject for developmental biology research. Research on fossil material and current ecology of mammals has opened up new perspectives into the research of tooth shape, food, ecology and climate.
