The Earth has been a mystery for as long as one can remember and a new research attempts to throw light on mass extinctions. It suggests that the planet is currently in the middle of mass extinction right now and losing thousands of species with each passing year. It also suggests that environmental changes caused
the first such event in history, which occurred millions of years earlier than scientists previously thought.

Most dinosaurs famously disappeared 66 million years ago at the end of the Cretaceous period.
