So what. It's not speaking that makes us intelligent it is reasoning.

True. But consider this: It's by communicating subtle & complex information to each other that we build a synergistic community (or even just a family or 2 partners in the hunting party, etc.) which greatly enhances our chances in the world. That could be a catalyst for the raw reasoning power to be more important to survival than it otherwise would've been.

Maybe?

All kidding aside, sure they are more advanced than dogs but so what.

They are way more limited that humans.

My dog understands about 30 words but I wouldn't start comparing him to humans that create whole societies.
