Q: How can we identify an extinction event?
A: Extinction events can be identified by observing a significant decrease in the number of species in a relatively short period.
Q: What is the purpose of a list of extinction events?
A: A list of extinction events provides an overview of the most prominent events in the history of life on Earth, which can help scientists to understand the patterns and causes of extinction.
Q: Are extinction events common?
A: Extinction events are relatively rare in the history of life on Earth, but they have had significant impacts on the diversity of species.
Q: Can extinction events be prevented?
