James Rollins did not take an easy topic to topic. Speaking of evolution based on theories that French readers unfortunately not yet had access is not easy. Like Jean Staune in "our existence does make sense?" Rollins proposes a reflection on the assumptions made by Mcfadden. Beyond the interest that can be worn to the question, the book is relatively well paced. To say that this is an essential book ... maybe. In other words, if you are particularly interested Evolution, go your way. If by cons you like to sénarios twists with a slight scientific reflexive frame, go for it! You will not be disappointed. Since 1945 to 2009, from the Himalayas to South Africa, primarily Rollins invites you to a trip.
