What reading level is Evolution book?
To quickly assess the difficulty of the text, read a short excerpt:

There is the ordinary "lethal selection, " which works by the discriminate elimination of the relatively less fit; and there is "repro- ductive selection, " which works through the increased and more effective reproductivity incident on the success of the more fit. When Darwin says "natural selection acts by life and death ... By the survival of the fittest and by the destruction of the less well-fitted individuals, " he describes lethal selection, and many use the term natural selection in thi...s sense only. But when Weismann says: "Those that are best adapted in colour will secure the most abundant food and will reproduce most prolifically, and they will thus have a better prospect of transmitting their usual colouring to their offspring, " he is obviously describing reproductive selec- tion.
Karl Pearson draws a distinction between "secular selection, " which is Darwin's natu- ral selection, and "periodic selection, " which is less easily detected. The difference is this: in the ordinary process of natural selection a change in the mean value of the selected character must be effected from one generation to another.
