Astronomers believe that the many supernova explosions that happened in the Milky Way Galaxy could have played a role in the evolution of life over billions of years. How would they have influenced the development of life on Earth?

Question

Quizplus · Accepted Answer

The cosmic rays produced by supernova explosions release high-energy particles and radiation that can penetrate Earth's atmosphere and influence the rate of mutations in cells, which can drive the process of evolution. This could have led to the development of new organisms over many generations, ultimately impacting the evolution of life on Earth. A and D are not accurate as supernova explosions can't affect Earth's crust or destroy other planets, respectively. B is not a valid explanation since humans did not exist at the time of supernova events. E is not entirely true as supernova explosions can have some impact beyond the star system they occur in, but their effect is limited.
