I've read an article from this link:

This article is about Earth's wobbly orbit that may cause climate changes and which, unfortunately does mass extinctions per 2.5 million years. I also read that it has been caused from asteroids that have been crashing on the Earth's atmosphere or orbit and has been stumping archaeologists about why this happens every 2.5 million years.
