What role does the process of mass extinction play in the evolution of life? What will be an ideal response?
When one species becomes extinct, that group’s habitat becomes available for another
organism. After mass extinctions, surviving organisms can rapidly expand and diversify,
occupying the niches that were temporarily vacant. A good example of this is the
diversification of mammals after the demise of dinosaurs at the end of the Mesozoic.
