The fossil record indicates that the teeth of many early hominids, particularly males, have wear grooves in certain locations between adjacent teeth. According to the most influential view, toothpick use explains the known distribution and anatomical placement of these grooves. Consequently, the wear grooves have been taken to hold important clues to early hominid diet and oral hygiene habits. However, the tooth-picking hypothesis may not be the proper explanation since ________.
Which of the following most logically completes the passage?
• some fossils of hominid children have been found with teeth free of wear grooves
• it fails to explain why wear grooves are found on some teeth of early hominids but not on some of their other teeth
• the grooves could just as likely have resulted from using the teeth to strip grain from stalks
• evidence shows that some female hominids had little access to foods that would stick in teeth
• modern toothpicks are designed in a way that does not cause wear grooves
