A trio of researchers at Simon Fraser University in Canada theorizes that ritualistic finger amputation during the Upper Paleolithic explains the number of missing fingers in depictions from that time. In their paper published in the Journal of Paleolithic Archeology, Brea McCauley, David Maxwell and Mark Collard outline the reasons for their theory, even as they acknowledge more evidence is required to prove it.
