Query: Gentle and simplistic

While the topic and content of this book seems interesting atfirst, the authors have presented the material in such a simpleway that it looks like if human evolution was so obvious andlinear. Most of the examples and works that support the viewpointof the authors seem to me quite ok, but the authors probably didnot read them thoroughly because they left much of their depthuntouched. What this book provides is merely inconsistent andunexplained information about aspects of humanity that are betterdiscussed elsewhere. So the value of reading this book might beto get you frustrated and make you go to the references of thebook, to get the original sources of the material of the book intheir full depth. But at least reading it from cover to coverwill not cost you much intellectual effort...
