Full network of clitoral nerves mapped out for first time
Fingers, for instance, not only have higher sensitivity, but also much higher spatial resolution due to the more dense nerve network.
I can't tell why other areas may have needed higher spatial resolution; maybe it was evolutionary important in the past, and remains today. Or maybe just adding more nerves due to a random mutation correlated with better reproductive outcomes due to a stronger signal, or higher sensitivity, so more nerves are present for no other reason.
