leaf and flower and habit which entitle them to 

 rank as different species. 



As the likenesses between the different daisies 

 are the tokens of their remote common origin and 

 evidences of the power of heredity, so their 

 specific differences betoken the influences of the 

 different environment in which they have lived 

 since they took divergent courses. 



The Japanese daisy is different from the Ger- 

 man daisy because the sum total of environ- 

 ment influences to which it has been subjected 

 in the past few thousand years is different from 

 the sum total of influences to which the German 

 daisy has been subjected. Xot merely differ-

 Germany to-day, but cumulative differences due 

 to ancestral environments all along the line of

 daisies eastward across Asia and the other branch 

 westward across Europe. 



Are Acquired Traits Transmitted? 



But all this implies that the imprint of 

 the successive environments was in each case 

 an influence transmitted to the offspring; and 

 this is precisely what I mean to imply. 



To me it seems quite clear that the observed 

 divergences between the European and the Jap-
