Question

Why do new species evolve more rapidly after a mass extinction?

Answer 1

Some factors may explain this phenomenon.

1. The reduction of predators: with the extinction of a predatory species, new species are more likely to reproduce.
2. The increase of food availability: with the decrease of other species, the new species has more food left over.
3. The reduction of competition: the risk of losing territory and food for competing species is reduced.

Answer 2
