I noticed that the question "Do we know why animals have evolved to have sex for reproduction?" was closed by the community. I am curious why this is the case, as I can't see any comments explaining directly how this question is off-topic.
I could of course just reopen it, but I think this case deserves some discussion. I think there is a perfectly viable and notable claim in that question, that we don't understand the advantage of sexual over asexual reproduction.
Should that question be reopened, or is there an argument I'm missing why this question is off-topic here?
