The question in question is: Why would terrestrial, rodent-sized sapient mammals evolve to be hairless?
Please correct me if I am mistaken, but worldbuilding SE has accepted questions of this sort for as long as I have browsed it (a good number of years before I made this account). Going over to the tag search and sorting by votes, you can find a highly comparable question appears to be well received - there aren't even any comments about it being under-specified. What is the difference between these questions that warrants closing? Is it simply that the culture has shifted in this time? I would be very happy to change my question, so long as the changes do not compromise its utility for the general public (which is the policy here, anyway, AFAIU).
Less comparable, but relevant example questions:
- Why did dragons evolve to be smart?
- What would be the evolutionary advantage for plants to be bioluminescent?
- Benefits of or reasons why a species would have only one eye?
- etc. It turns out there are quite a few of these even when I restrict it to ones roughly as vague as my own and without comments suggesting it should be closed on those grounds.
