The fingers of the human palm exhibit a (bi)symmetrical pattern with regards to their size, in the sense that the thumb and the pinky are almost the same size, and the same holds for the index and ring finger. I was wondering what the biological imperatives and/or evolutionary advantages behind this physical characteristic are.
The only rationale I personally am able to come up with is that this particular arrangement might be optimal or ideal for grasping, handling, and manipulating objects, but am unsure of its truthfulness, and, even if correct, I would still be interested in exploring other possible avenues.
