the reason humans have 5 toes and 5 fingers of the hand

hallo stemian..

wowfakta Are if there are 12 each will make us work more effectively?

Surely we all realize how precious a thumb finger is. Without a thumbnail whose location is unique then we will need to fight hard to open a set of biscuits.

Then what about the other fingers? How would it be if we reduced or increased the amount?

There is a formula used by biologists called Limbs Law to predict the number of fingers of mammals. The shorter each finger, the more number of fingers it needs. There are some babies born with more than 10 fingers.

Usually the excess finger will be removed by using surgery. Saintis also believes that for mammals like us, 10 is the right amount.

Excess finger will only make the job less effective. While in the case of robots, 2, 3, or even just 4 fingers on one hand has made their work very optimal.
