In what animals would I on priors expect intelligence to evolve?
Animals which use collaborative hunting techniques.
Large animals. (So the neurons make up a smaller share of the overall metabolic cost.)
Animals that can use tools so they benefit more from higher intelligence.
(perhaps some other stuff like cultural knowledge being useful, or having enough slack for intelligence increase from social dynamics being possible.)
AFAIK, orcas are the largest animals that use collaborative hunting techniques.[1] That plausibly puts them second behind humans for where I would expect intelligence to evolve. So it doesn’t take that much evidence for me to be like “ok looks like orcas also fell into some kind of intelligence attractor”.
Though I heard sperm whales might sometimes collaborate too, but not nearly that sophisticated I guess. But I also wouldn’t be shocked if sperm whales are very smart. They have the biggest animal brains, but I don’t whether the cortical neuron count is known.
