Download or read book Retrograde Evolution During Major Extinction Crises written by Jean Guex and published by Springer. This book was released on 2016-02-05 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind, providing in-depth analysis of the retrograde evolution occurring during major extinction periods. The text offers a non-strictly adaptative explanation of repetition of phyla after the major extinctions, utilizing a study of seven phylogenetically distinct groups. This opens a new experimental field in evolutionary biology with the possibility of reconstructing ancestral forms in lab by applying artificial stresses.
