AustraliaA study suggests that bumblebees may express preferences through facial movements, potentially indicating emotional states. Published in the Proceedings of the National Academy of Sciences, the research explores whether insects exhibit signs of internal experiences akin to human emotions. The findings build on historical discussions by Charles Darwin and modern neuroscience, which have linked facial expressions in mammals to emotional states. Researchers observed bumblebees' mouth movements when tasting sugar and salt solutions, noting behaviors resembling human expressions of enjoyment and disgust. Further tests were conducted to determine if these responses were purely physiological or indicative of more complex cognitive processes.
