A theory suggests that we have 5 fingers because together they make a perfect strong grip. Using them, we can operate small objects with great control and precision.

Second theory suggests that 3 molecules called Bmp, Wnt and Sox9 are responsible for the five fingers, since in our embryonic stage, they mark out spaces specifically for these 5 fingers.

Another theory is related the Limb law. Based on the length of the fingers, this law helps us calculate the number of fingers we should have. Now, limb’s law using its mathematical model comes up with the answer 9.42 fingers per hand. But we need fingers only on 1 side of the palm as other side is connected to an arm. Hence, the final answer comes out to be 4.78, that is, 5 fingers per hand.
