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
The ratio of a man’s ring finger to his pointer finger is proportional to the amount of testosterone received in the womb. The longer the ring to the pointer, the more test.
A researcher was able to calculate ratios and use this information to accurately predict who would win in a short foot race between healthy males of similar age.
