I wonder, what did the first humans do with their toenails? Okay, you could bite off the ones on your hands since there were no scissors yet, but the toenails? Again, there were no stones or asphalt; they would wear down extremely slowly when rubbing against the ground. Running from predators or chasing them with such nails would certainly be inconvenient. The only reasonable explanation is that relatives, friends, and partners gnawed off each other’s toenails.
