A huge gap separating the truth and legend, and this is what makes it vulnerable to manipulation and control. The nineteenth century history shows how Darwin's theory was distorted to give it a "scientific" character that justifies colonialism. Where the laws of nature were distorted to claim that the whiteness is the only way to survive. This book stands in the face of these racist ideas and exposes the myths on which they were built. It begins to deny the legend of the retreat of mixed breeds and pass through the myth of slavery and the Negro sex, then the Jewish and Nazi myths. To reach the imagination with the truth with the "super man". The author offers the reader a scientific view showing that biological differences between humans do not justify oppression and discrimination.
