Humans still evolving only 30,000 years ago

The skeleton of a child from 30,000 years ago has given us greater insight into the anatomical evolution of modern humans. The teeth of this child were x-rayed (is that even a word?) using a technique called micro-tomography that creates a digital 3D reconstruction of an object. They discovered that in comparison to the molars, the incisors were not as well developed, and had more dentin and pulp, but less enamel than the teeth of modern humans.
