Revealing mistake: Most of the posed, fake displays in the ape's Museum of Natural History contain real people who are slightly moving if one pays careful attention. Especially noticeable are those posing with objects held in - or above - their hands.

Question: Why do the humans in "Planet Of The Apes" all wear clothes? I am fully aware that the film was made in 1968, for a general release, permitting it to be shown in cinemas or on television, and 20th Century Fox would never have been allowed to make a movie in which humans all ran around naked. But, since the film is supposed to be set in a post-apocalyptic world, where humans have regressed back to being wild creatures, without language, lacking the skills to make or create anything, where do they get their clothes from? (And their clothes fit, too.) Did anybody ever come up with an answer to this, apart from the obvious reply that they wanted to get the film past the censor?
Answer: The humans have become mute, but not regressed to being "wild animals." The apes are the superior species but humans still have a high-level of intelligence, live in a complex, interactive social group, communicate non-verbally, and would have the ability to make simple tools and protective clothing. At the very least they would be equal to Neanderthals, but seem more advanced. The real answer is, of course, it's a 1968 movie when there were more stringent rules regarding nudity in films. If there was any, it likely would have been "X" rated, therefore limiting its audience and in which theaters it could have been shown in.
Answer: Unlike other primates, humans walk upright which exposes their genitals. They would instinctively cover them for protection. Humans also have very little body hair, so would cover themselves against the elements. Finally (spoiler alert) as these humans devolved from actual humans, it's likely something they did because their ancestors did it and it's been continued through the generations.
