Why are all our fingers different lengths? wouldn’t it be better if they were all the same length?
In: Biology
We don’t know. The theory I always heard is that it makes it easier to grip round objects, like fruits. To see why this would work, try to line up your fingertips and look at the cavity shape your hand forms.
But there are other theories. That it makes it easier for us to grip tools, or to throw things, or to form a fist, just to name a few. It could even be some combination of factors. Or even an evolutionary vestige, as other commenters have suggested. But we don’t know for sure.
