Why are mass extinctions an important part of Earth's evolutionary history? It removes toxins from the plant life it removes predators from the environment it changes the dimosphere allows for the availability of new life to evolve in its place

## Step 1<br />Mass extinctions are significant events in Earth's evolutionary history. They are characterized by the rapid a large number of species in a relatively short period of time. This is usually due to catastrophic events such as volcanic eruptions, climate change, or asteroid impacts.<br /><br />## Step 2<br />The primary reason why mass extinctions are important is that they allow for the availability of new life to evolve in its place. When a large number of species are wiped out, it creates a vacuum in the ecosystem. This vacuum provides an opportunity for new species to evolve and fill the niches left by the extinct species.<br /><br />## Step 3<br />The other options provided, such as removing toxins from plant life, removing predators from the environment, or changing the atmosphere, are not the primary reasons why mass extinctions are important. While these events may have some impact on the environment, they are not the main reason why mass extinctions are significant.
