known species with a human level of higher intelligence
- Humans (allegedly; evidence points to most being dumb as a rock).
- Some species of extinct hominids (sure, but they're extinct).
- Dolphins (and orcas, which are big fancy dolphins); absolute creeps, though.
- Whales, possibly, though they tend to keep to themselves, so who knows.
- Some species of octopods.
- Some species of parrots.
- Some species of corvids.
- I swear some of those black and white sheepdogs seem more intelligent than many of the people I know.
