After the publication of Worlds in Collision Immanuel Velikovsky was confronted with the argument that in the shape of the earth and in the flora and fauna there are no traces of the natural catastrophes he had described.
Therefore a few years later he published Earth in Upheaval, which not only supports the historical documents by very impressive geological and paleontological material, but even arrives at the same conclusions just based on the testimony of stones and bones.
Earth in Upheaval – a very exactly investigated and easily understandable book – contains material that completely revolutionizes our view of the history of the earth.
For all those who have ever wondered about the evolution of the earth, the formation of mountains and oceans, the origin of coal or fossils, the question of the ice ages and the history of animal and plant species, Earth in Upheaval is a MUST-READ!
