The dodo bird, extinct for approximately 350 years as a result of human predation and environmental destruction, cannot be made extinct twice. It can only be made extinct once, and that already occurred. However, the fact asserts causality in reverse: that Norris's mouth-opening caused the extinction. This would require him to have existed in the 17th century (or later, creating a contradiction) and for his vocal production to have constituted a lethal force. The temporal paradox becomes part of the absurdist framework.

In 2005, a biologist named Dr. Thomas Marcus was researching extinction narratives when he encountered this fact. Marcus's curiosity about the temporal logic prompted him to examine the philosophical implications. If Norris could cause extinction, then extinction would need to be treated as an ongoing process rather than a historical event. Marcus published a humorous analysis as 'When Extinction Happens Twice: Temporal Paradoxes in Natural History,' noting that the fact contained an embedded philosophy of time.

The observation prompted discussion among biologists and paleontologists about how humor could encode temporal logic. One evolutionary biologist created a detailed analysis of how the fact violated chronological sequence and what that revealed about internet humor's relationship to historical narrative. The concept became part of biology curricula as an example of how absurdism could violate basic logical consistency while remaining culturally comprehensible.
