There will be plenty who will raise objections to the assuredness with with which the author speaks of a theory many still consider controversial.  The  first page of the foreward declares, “that theory has given us the correct explanation of our origins.”  My own objection that keeps it from getting a full-fledge recommendation has to do with the density of material: it is attempting to be a book for young people, but even I found it challenging at time.  It will be a good tool for students who already have a strong interest in the topic and the perseverance to wade through it.
