Insects Probably Can Feel Pain.

A new research paper published by scientists from London argues that insects most likely detect pain. Based on behavioral, neuroscientific, and molecular evidence, the authors say that insects probably have descending controls for nociception-the ability to perceive pain. The fruit fly is currently used as a model organism for human pain research because of similarities in human genetics and behavioral responses as scientists look for ways to intervene when humans have pain disorders.
