The team looked elsewhere for evidence of finger amputation in other societies and found more than 100 instances where it had been practised. “This practice was clearly invented independently multiple times,” they state. “And it was engaged in by some recent hunter-gatherer societies, so it is entirely possible that the groups at Gargas and the other caves engaged in the practice.”
Collard pointed to rituals still carried out in Mauritius and other places, such as fire-walking, face-piercing with skewers and putting hooks through skin so a person can haul heavy chains behind them. “People become more likely to cooperate with other group members after going through such rituals. Amputating fingers may simply have been a more extreme version of this type of ritual.”
