Why aren’t our fingers the same size? Like how come most people are born with the ring finger splitting the difference between the index and middle? I know it’s like natural selection and stuff but why did it benefit us for our fingers to be how they are?!
In: Biology
An interesting parallel is the amount of brain area that is dedicated to the control of each finger. The thumb probably has as much brain driving it as the rest of the hand. The index finger is next in line.
