A new study by an international team of anthropologists took a fresh look at the teeth of humans and fossil hominins and confirmed that molars, including wisdom teeth, do follow the sizes predicted by what is called "the inhibitory cascade" -- a rule that shows how the size of one tooth affects the size of the tooth next to it.
The research is important because it indicates that human evolution was a lot simpler than scientists had previously thought. This is a cast of the skull of Lucy, the australopith Australopithecus afarensis from Ethiopia, was included in a study that found the evolution of human teeth is much simpler than was previously thought.Image credit: David Hocking, Monash University
