END OF EVOLUTION MASS EXTINICT & BIODIVERSITY by WARD,PETER is a brilliant look into the history of planet Earth and the life that once inhibited this planet. Throughout the history mass extinctions have occured resulting in the destruction of old world also resulting in the evolution of a new world. Throughout the book Dr. Ward describes these mass extinctions and warns of another mass extinction that may take place if Human Beings are not careful. I strongly advice anyone who is remotely interested in Geology or in any sciences to read this book!
