This collection of discussions demonstrates high engagement and interest, with phrases like 'significantly different from background extinction' and references to the original research by Raup and Sepkoski. The tone varies from appreciative remarks about learning from history to critical comments about the fossil record and scientific definitions, which reflect a nuanced understanding and appreciation of the significance of the research.

AgreementModerate agreement

Most posts acknowledge and relate positively to the scientific publication, reflecting a general agreement or appreciation of its significance.

InterestHigh interest

Discussions indicate high interest, with posts referencing multiple mass extinctions, methods, and historical context, showing active engagement with the topic.

EngagementModerate engagement

Several posts go beyond simple agreement, discussing concepts like the nature of mass extinctions and related scientific studies, indicating moderate engagement.

ImpactModerate impact

While some posts highlight the importance of understanding extinction events, few suggest that this discussion is transforming public perception or policy, hence a moderate impact score.

Abstract in brief

  • Four major mass extinctions in marine life occurred during the late Ordovician, Permian, Triassic, and Cretaceous periods, significantly higher than normal background extinction rates.
  • A fifth extinction in the Devonian is notable but not statistically significant based on the fossil data.
  • Overall, background extinction rates have decreased since the Cambrian period, likely because species have become better at surviving over time.]

@BaranKarapunar In my understanding the cut-off will always be arbitrary, and that's why in my understanding any global scale event that affected multiple groups could be called a mass extinction.

So it seems, there’s been several extinction events across Earth’s history. Statistically we aren’t alone in this universe so perhaps we aren’t such a fluke as a species. https://t.co/GOIF0bbrMt https://t.co/LpYIJ19iTk
