I thought this book more difficult to access easily but in fact we follow the author's reasoning is careful not to lose its drive. Certainly there sometimes lengths particularly in the chapter on aggression and when the author describes an animal's genes in common with other members of his family. According to him, many behaviors are generated by genes but with the exception of the beginning of the book, he speaks quite a few pure genetics. How genes make us react? by what means exactly? these issues are little abordées.RD Describes especially Darwinian behaviors that promote the survival and propagation of genes (altruism, leakage gazelle ...). Although these conclusions were nuanced by later discoveries, this book remains a reference that any one who is interested in this subject must have read.
