Do modern humans have Megadontia?
While Post canine megadontia denotes the enlargement of the premolars and molars found in early hominid ancestors, it did not affect the structural organization of the cusps that make up those teeth, and thus, were used similarly to the premolars and molars that modern humans possess today.
