Around 65 million years ago, 95 percent of the planet's species are wiped out, and the age of the dinosaurs ended. Which of the following best explains why we still have numerous species today?

• The species that exist today were those that were not wiped out when the dinosaurs died.

• The species that exist today evolved from surviving species to fill niches left vacant by dinosaurs.

• The species that exist today speciated due to separation among different populations

• The species that exist today have the potential to a be as numerous as the ones that went extinct.
