>>13334069>Fur causes animals to overheat while running during the day, but without it they lose too much body heat at nightPlenty of human-weight african mammals have very little hair and no fur. Some Warthogs for example have no fur and very little hair, like maybe a greek person amount. Hence, fur is not a necessity at night in the locations you seem to describe such as Africa where you probably assume humans lost their fur.
>When our brains got big enough to invent clothing we were able to break the rules and stay cool during the day without freezing at night.Why would we invent clothes if our fur was already doing the job?
Even venturing into colder climates still would not select for no fur if you have clothes. It's preferable to grow your own fur instead of making your own clothes. We have constantly growing hair on our heads, it's not like the resources for fur are super utterly critical and should be saved if at all possible.
Also, obviously, undeveloped black people in African jungles and savanna plains don't freeze to death at night because their huts or "clothes" keep them warm; it's because it doesn't get that cold.
You have not listed an incentive for nature to select for no fur in humans just because humans got smarter.
