I am unaware of any theories that we came from "apes."
When you put "apes" in that context, it makes the theory of evolution seem less credible, and more ridiculous than it deserves.
I would suspect we lost our fur as a result of being in a temperate climate, and being in need of vitamin D.
Also, a genius among us learned to weave, and/or wear the fur of animals we scavenged or killed.
Personally, I entertain the notion that we are descended from primates that were inseminated by very horny, possibly intoxicated space aliens.
Can you imagine what a hilarious scene that would be? I can imagine the hung-over space aliens waking up, realizing what they'd done, doing a walk of shame, crawling and vomiting their way onto their ship, and leaving the scene at warp speed.
I think they visit us from time to time in order to observe us and re-affirm what an embarrassing, terrible, stupid thing they did. The infamous incident probably set a precedent for the protocol to follow when visiting the natives of other planets.
Rule #1: don't have intercourse with the natives.
That theory is no less ridiculous or incredible than plenty of stories from any text.
