ABSTRACT
The evolution of the living world has not been straightforward process over geological time. On the contrary, it shows episodes of crises separating phases of evolving radiation. This work, presenting an assessment of the paleontological discoveries of the last fifteen years, could be summed up by the formula "the evolution of life on our planet or biodiversity". This book, which combines clarity of presentation with scientific rigor, will be of interest to biologists and geologists as well as teachers, students and all those wishing to extend their knowledge on the subject.
