Scientists put human gene into monkeys, . . .
. . . to make them smarter, human like.
So poor old DonDiego's thinking haven't these scientists seen how this turns out in the movies, . . . think "Dr. Zaius" ! Not a good idea.
And then poor old DonDiego's day got worse ! He came across a story which, in contexrt with smarter human-like apes, pretty much assures the demise of mankind: College promotes men's cuddling group to 'redefine masculinity'.
Well, . . . all things considered it was a pretty good run, . . . and mankind did leave evidence of making it to the Moon before the pendoing downfall, so at least there's that.
