Which of the Following Is Not Thought to Have Contributed

Which of the following is not thought to have contributed to the many mass extinction events that have occurred throughout Earth's history?

A) plate tectonics
B) habitat loss
C) meteorite impacts
D) continental drift
E) punctuated equilibrium The movement of continents continental drift) as a result of plate tectonic activity is thought to have greatly reduced some types of habitats and contributed to mass extinction events at various times. Likewise, cataclysmic events such as a meteorite impact may have caused the mass extinction of the dinosaurs. Only the punctuated equilibrium model, which merely suggests that species tend to remain mostly the same for long periods of time before rapidly evolving, is not a cause of mass extinction events.
