Why do humans have 5 fingers? Why not 4 or 6?
Can you tell me why humans have 5 fingers? Why not 4 or 6?
Humans have 5 fingers because it is believed to have evolved as an adaptation to our ancestors' tool-making ability. The opposable thumb allowed our ancestors to grip objects better while the other fingers allowed them to hold and manipulate the tools.
