The more we study dolphins, the brighter they turn out to be (2003)

Of course they might be a bit peeved when they find recipes for themselves on the Internet.
My roundabout point is, why do they have to build civilizations? Because we humans think that's the pinnacle of advancement? Perhaps the dolphins have a difference in opinion. Perhaps they're debating this very idea over some delicious herring: "do you think humans are intelligent?"
"Mmm, could be. But they keep scurrying around building pointless crap, so I don't know."
"Yeah, good point. More herring, darling?"
Dolphins are not turning out to be brighter. They were/are as bright as they always have been. Humans are the ones changing, losing a bit more of our ignorance and hubris.
This is still so pervasive that most people don't even recognize that as an "issue". Just like people hundreds of years ago wouldn't be phazed by the title "Negroid race is turning out to not be savage sub-humans after all".
"The more we study dolphins, the brighter they turn out to be" is obviously not saying our study causes them to become more intelligent.
If anything, it's implicitly acknowledging that we're not as exceptional as we'd like to think.
The title doesn't even indicate that the dolphins' brightness is changing, but rather that we're increasingly perceiving them as bright.
