374 THE HISTOEY OF CREATION. 



islands were peopled; lastly and thirdly, the peculiar 

 character presented in general by the flora and fauna of 

 islands taken as a whole. 



All these chorological facts given by Darwin, Wallace, 

 and Wagner — especially the remarkable phenomena of the 

 limited local fauna and flora, the relations of insular to conti- 

 nental inhabitants, the wide distribution of the so-called 

 "cosmopolitan species," the close relationship of the local 

 species of the present day with the extinct species of the 

 same limited territory, the demonstrable radiation of 

 every species from a single central point of creation — all 

 these, and all other phenomena furnished to us by the 

 geographical and the topographical distribution of organisms, 

 are explained in a simple and thorough manner by the 

 theory of selection and migration, while without it they are 

 simply incomprehensible. Consequently, in the whole of 

 this series of phenomena we find a new and weighty proof 

 of the truth of the Theory of Descent.
