A
Correct answer
Explanation
The Permian-Triassic extinction event, also known as the 'Great Dying', was the most severe extinction event in Earth's history, resulting in the loss of approximately 96% of marine species and 70% of terrestrial vertebrate species.
What is the estimated number of species that went extinct during the Cretaceous-Paleogene extinction event?
B
Correct answer
Explanation
The Cretaceous-Paleogene extinction event, commonly known as the Chicxulub impact, is estimated to have caused the extinction of approximately 75% of all plant and animal species on Earth, including the non-avian dinosaurs.
