Animal behaviour: Inside the cunning, caring and greedy minds of fish (nature.com)

This is not just about fish. It's research that challenges a lot of established beliefs about what sets primates apart. Not just observation, but testing. Great article, really interesting.

This is really mind blowing.

I don't understand the suggestion that cooperation and complex social systems are the province of primates. Haven't they heard of dogs, cats, pigs, deer, or the countless other animals that hunt or defend themselves cooperatively, and which have complex hierarchies in group behavior?

This type of thing is why I have been saying for a few years that AGI researchers should really be trying to emulate the true capabilities of simple animals first rather than humans.
