Chimps are generally considered more intelligent than gorillas.

Bottlenose Dolphins have 11-15b cortical neurons while humans are in the range 14-18 (range is measurement uncertainty). It's also worth noting these dolphins have a larger brain mass (1.6 kg) and larger cortical surface (3700 cm2) than humans (1.3 kg and 2400 cm2, respectively).

So more than scale. Glad we agree. Seems you also agree that architecture matters too.

And chimps are genetically more similar to humans than gorillas. A chimp brain is more similar to a human brain than a gorilla brain.

We absolutely do not agree. Notice how nobody suggested that a human brain is a scaled up version of an axolotl's brain? Yeah, that didn't happen. I do wonder why?
