Wasps That Recognize Faces of Other Wasps Cooperate More, May Be Smarter

new study of paper wasps suggests social interactions may make animals smarter. The research offers behavioral evidence of an evolutionary link between the ability to recognize individuals and social cooperation. The article, published December 7, 2023 in Current Biology, is titled “Evidence for a Selective Link Between Cooperation and Individual Recognition.” Furthermore, genomic sequencing revealed that populations of wasps that recognized each other – and cooperated more – showed recent adaptations (positive selection) in areas of the brain associated with cognitive abilities such as learning, memory, and vision.
