Weird questions, but basically the title. Is there any reason why human fingers are different lengths?
This originally became a question because of some sh**post I saw claiming if certain fingers were longer than others it means you more likely to be more “endowed”.
But it did get me thinking; is there a biological explanation for varying lengths in fingers? I’ve often heard that phrase “good enough” used in evolutionary explanations, but I’m genuinely curious if finger-length was a “good enough” evolution or it had a purpose at some point (or even today that I’m not noticing).
