Wait, so fossil records and carbon dating is wrong based on this study? I am not convinced to be honest. And lol at last sentence kind of debunking original statement - "Such times give rise to sweeping genetic changes across the planet, causing new species to appear. However, the last time such an occurrence took place was 65 million years ago, when an asteroid hit the Earth and killed off the dinosaurs and half of all other species on the planet".
So after dinosaurs were wiped out only 10% of the animals appeared for whole 65 milion years on Earth but then another 90% suddenly appeared 100-200k years ago? I smell BS.
