You seemed to have left off the second part of the sentence, which you appear to agree with
"No other species points, Novack explained, not even chimpanzees or apes, according to most reports, unless they are raised by people"
edit: I suppose the clause "unless they are raised by people" could be interpreted as pertaining to either "not even chimpanzees or apes", or "No other species", but I don't think it matters.
Elephants seem to understand pointing without being trained. It's possible that they point too.
> We suggest that success was not due to prior training or extensive learning opportunities. Elephants successfully interpreted pointing when the experimenter’s proximity to the hiding place was varied and when the ostensive pointing gesture was visually subtle, suggesting that they understood the experimenter’s communicative intent.
Possibly not, since we're pretty good at following another person's gaze instead. And different cultures point differently. I knew a guy who lived in Papua New Guinea for a while and he had to untrain himself to point with his finger. People there would just look at his finger. They only pointed with their chins.
