Amongst Cuvier's successful contributions to the understanding of the fossil history was creating extinction to be a truth. In an try and explain extinction, Cuvier proposed the concept of "revolutions" or catastrophism wherein he speculated that geological catastrophes had transpired all through the Earth's historical past, wiping out big numbers of species.
