A study conducted byUniversity of Michigan biologist Elizabeth Tibbetts, found that paper wasps can determine which opponents are the weakest by watching them fight with another wasp. According to the study, “fighter” wasps were placed in a small container while two “bystander” wasps observed the pair through clear plastic partitions. The scientists found that bystander wasps were more aggressive when paired with an individual that was the victim of lots of aggression in a previous bout, as well as individuals who initiated little aggression in the previous fight.
The research also illustrated that the wasps can recall what they saw for a long time. This study shows a few interesting points. First, small brains, which were previously thought to be less intelligent, are not necessarily so. Also that wasps are capable of a rather complex thought process that includes analyzing what they saw, remembering it, that they recognize and can categorize individuals.
If wasps can do this, imagine what other animals are capable of? How should that affect our training methods for our pets and other animals? How does human interference affect wildlife?
