If some future generation of humans spontaneously evolved to have pointed ears, would that result in solo elf images becoming human_only?

We DO have ear points (at least some percent of the population) they just don't point up, they're like a triangle bump on the inner curve of your ear. Darwin used it as an example of a vestigial trait in humans (I have it on one ear but not the other, myself, so it's not always both). So I guess elves just mutant humans 😔
