Answer 1

One thing to keep in mind when asking questions about our evolution is that things aren’t always advantageous. Sometimes they just aren’t disadvantageous and that’s good enough. If there’s a mutation and it doesn’t negatively affect the ability to survive and procreate, it might just stick around.

Not saying that applies in this case, but rather, suggesting it’s always good to challenge the assumption that something may be advantageous just because it exists.
