Understanding and emulating a very simple brain could be the key to understand how intelligence/learning works and this knowledge (algorithms) could be applied to Artificial intelligence. "Insects certainly display complex and apparently intelligent behavior. They navigate over long distances, find food, avoid predators, communicate, display courtship, care for their young, and so on. The complexity of their behavioral repertoire is comparable to any mammal."
