102 THE EVOLUTION OF MAN. 



published a work on " Man, his Descent and Civilization, iu 

 the light of the Darwinian Theory." 



At the same time, in the second volume of my Generelle 

 Morphologie der Organismen, which appeared in 1866, I 

 made the first attempt to apply the Theory of Evolution to 

 the entire classification of organisms, including Man.^^ I 

 tried to sketch the hypothetical genealogies of the dif- 

 ferent classes of the animal kingdom, of the kingdom of 

 Protista, and of the vegetable kingdom, not only as they 

 must be according to the principles of the Darwinian 

 Theory, but also, as it is already really possible to do, with 

 a certain degree of probability. For, if the Theory of 

 Descent, as first definitely stated by Lamarck, and after- 

 wards firmly established by Darwin, is correct in its general 

 principles, then it must also be possible to interpret the 

 natural system of plants and animals genealogically, and to 

 place the smaller and larger divisions recognized in the 

 system, as limbs and branches of a genealogical tree. The 

 eight genealogical tables which I appended to the second 

 volume of the Generelle Morplwlog'ie, are the first attempts 

 to accomplish this. In the twenty-seventh chapter of the 

 same work are given the most important stages in the 

 ancestral line of the human race, as far as they can be 

 traced in the descent of Vertebrates. I there attempted 

 especially to determine the place in the mammalian class 

 assigned to Man by the system, and, as far as seems possible 

 at present, the genealogical significance of the latter. In 

 the twenty-second and twenty-third chapters of my " His- 

 tory of Creation,'' I materially improved on this attempt 

 and explained it in a more popular form. 



At last, in 1871, Darwin himself published a very in-
