From the article:
> These bees retrieved their spatial memories entirely out of context, at a time when there was no possibility of foraging and so no immediate need for communication. The function is unclear. They might have ‘just thought’ about these locations spontaneously during the night. Or perhaps the communication is a strategy for consolidating their spatial memory. Scientists have since found that a bee’s memories of the previous day are strengthened when they are exposed to elements of these memories while in deep sleep. Perhaps bees not only think and ‘talk’, but dream?
> The key implication of Lindauer’s discovery is that bees are capable of ‘offline thinking’ about spatial locations, and of linking these locations to a time of day, in the absence of an external trigger. That’s not what should happen if bees’ memories are merely prompted by environmental stimuli, combined with internal triggers such as hunger. Bees, then, appear to have at least one of the principal hallmarks of consciousness: representations of time and space.
That sounds like evidence that bees may be capable of "reason[ing] abstractly".
What can humans accomplish using solely "intelligence" that other animals can't?
All of the unique behaviors I see in humans involve use of fire-derived technology.
