Despite many clear allusions to several world religions, Ingrid Reichel says that the novel is a book for “readers with humor, for reasoners (…), for darwinists, on no account for creationists, to a lesser extent for people of faith, but rather for atheists, … and fundamentalists drop out entirely”. Another aspect is identified by Karin Gayer when mentioning the parallel evolution of the patriarchal hierarchy in the story's society and the social matriarchy, the first resembling Chimpanzee communities and the second those of Bonobos. In addition, she points out the strength of the women characters. With regard to these underlying comparisons she says: “On another level we are struck by the permanent verbal mix of the ape-like and the human, a combination which leaves us pensive and asks the legitimate question where we, who consider ourselves sapiens in a double sense, should finally classify man.”.
