This is a beautiful book--the best book I have ever read dealing with the
Origin. It will move many people, experts and lay readers alike.--Lee Alan
Dugatkin, author of Principles of Animal Behavior The Origin Then and
Now has made the wealth of information held within Darwin´s opus many times
more accessible. This book is unquestionably essential reading for students and
others approaching the Origin for the first time. It should be terrifically
useful to anyone with an interest in understanding one of the most important
books in intellectual history.--Kurt Schwenk, University of Connecticut
