Maybe the joke was, they are the ones that seems closest to the homo species but are still apes?
That sentence makes no sense. Chimps and humans are both apes.

Not only are chimps the closest relative to humans, but humans are the closest relative to chimps.
And mention things like polyamory. I was 40 before realizing that was an option…
