• Language Connection: Researchers discovered a neuronal connection related to language in chimpanzee brains, previously thought to be unique to humans.
• Arcuate Fasciculus: The arcuate fasciculus links language areas in the brain; this connection exists in chimpanzees but is weaker than in humans.
• Evolutionary Insight: The study suggests that the architecture for complex communication existed in the common ancestor of humans and chimpanzees about seven million years ago.
