The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
So, all the things you talked about, the breathing, the grunting and so forth, a lot of that is handled by the brain stem circuits, you know, right around the level of your neck and below. Like a reflex kind of thing. So, or even some emotional aspects of your behavior in the hypothalamus and so forth. But for a learned behavior, learning how to speak, learning how to play the piano, teaching a dog to learn how to do tricks is using the forebrain circuits.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
And what has happened is that there's a lot of forebrain circuits that are controlling, learning how to move body parts in these species, but not for the vocalizations. But in humans and in parrots and in some other species, somehow, we acquired circuits where the forebrain has taken over the brain stem and now using that brain stem, not only to produce the innate behaviors or vocal behaviors, but the learned ones as well.
