Social bugs like bees exhibit a exceptional vary of behaviors, from working collectively to construct structurally complicated nests (full with built-in local weather management) to the pragmatic division of labor inside their communities. Biologists have historically considered these behaviors as pre-programmed responses that advanced over generations in response to exterior components. However two papers final week reported outcomes indicating that social studying may additionally play a task.

The primary, printed within the journal PLoS Biology, demonstrated that bumblebees might study to unravel easy puzzles by watching extra skilled friends. The second, printed within the journal Science, reported proof for related social studying in how honeybees study to carry out their trademark “waggle dance” to inform different bees of their colony the place to search out meals or different sources. Taken collectively, each research add to a rising physique of proof of a sort of “tradition” amongst social bugs like bees.

“Tradition could be broadly outlined as behaviors which can be acquired by social studying and are maintained in a inhabitants over time, and primarily serves as a ‘second type of inheritance,’ however most research have been performed on species with comparatively massive brains: primates, cetaceans, and passerine birds,” stated co-author Alice Bridges, a graduate pupil at Queen Mary College of London who works within the lab of co-author Lars Chittka. “I wished to review bumblebees particularly as a result of they’re excellent fashions for social studying experiments. They’ve beforehand been proven to have the ability to study actually complicated, novel, non-natural behaviors similar to string-pulling each individually and socially.”
