@datarama What I mean is that a honeybee is likely to be similar to a solitary bee, but ALSO eusocial. Not a separate development that is completely different from solitary bees and wasps and much stupider than them.
Human intelligence is affected by social setting more than is acknowledged BTW. Both positively and negatively. A PhD in quantum physics, for instance, can destroy an individually promising cerebral cortex that could have flourished with a degree in, say, chemistry.
