Quite interesting to see this being done with bees, but the statement "The study [...] shows how animals may be able to able to pass on skills in a way we previously thought was largely exclusive to humans" is very misleading. Observational learning has been observed in many other animals before, humans aren't particularly special at all in that respect.
I.e learning behaviours by observing another animal be rewarded or punished for a behaviour.
