"Surprising Collective Intelligence: Bees and Chimpanzees Learn Complex Behaviors Like Humans"
Bumblebees have demonstrated a level of collective intelligence in experiments that was previously thought to be unique to humans. They were trained to open a two-step puzzle box and then taught the solution to other bees, challenging the idea that socially learned behaviors are exclusive to humans. This finding suggests that the ability to learn from others what cannot be learned alone should now be considered a common trait across species, not just humans. The study was published in Nature and sheds light on the underestimated intelligence of bumblebees.
