<em>A. Mass extinctions, the complexity of life, and oceanic movement
</em>
<em></em>
<u>Explanation:</u>
Mass extinction is the most striking pattern that existed in the fossil records over many years. Most species disappearrandomly across the world. Therefore extinction requires global environment because it is severe and rapid and cannot evolve; instead, it goes.
Multiple numbers of species are the sources of innovation also increase instead of fighting the cold ones species. However, according to evolution, there is another creative destruction where the destruction creates a vacuum and drives the creation of something new and better.
