According to research conducted by Richard Bambach, a paleontologist at the Smithsonian Institute, and Adrian Melot, a famous British astronomer, every 27 million years, a major extinction of life on Earth takes place. The same calculations show that the next wave of extinction of living species will take place over about 16 million years, according to British media.
“Numerous fossil data we have shows that such events occur in 99% with an interval of 27 million years. What is the right mystery is why they happen “”said Richard Bambach.
