Quizplus · Accepted Answer

A nonhoning canine is a trait that developed after hominids began making and using tools for food processing. Hominids with nonhoning canines have evolved to have smaller and shorter canines, which don't sharpen against other teeth like honing canines do. Therefore, the presence of a nonhoning canine in the skull would indicate that this individual lived after hominids began making and using tools for food processing.
