Dr. Steven Hamblin introduces himself as an evolutionary biologist, not a medical doctor. He then discusses evolution and how keeping animals in circuses can negatively impact the animals. Specifically, he explains that the training methods commonly used in circuses, like punishment and negative reinforcement, can lead animals to experience aggression, physical harm, fear, and learned helplessness. The animals are also denied their natural behaviors by being confined to small spaces instead of their usual large home ranges.
