LINNAEUS TO LAMARCK 35 



previous species changed in adapting them- 

 selves to a changed environment. 



But Lamarck has another claim to a niche 

 in the Pantheon of Science. As the conviction 

 gained ground that species were not fixed and 

 immutable as they came from the hands of an 

 alleged creator, but were the products of an 

 evolutionary development extending through 

 immense periods of time, another question 

 arose and called for an answer. That question 

 was — "By what process?'' 



Charles Darwin is the most illustrious of all 

 the sons of science because he answered that 

 question. Lamarck gave an answer, and the 

 question as to whether that answer is entitled 

 to be incorporated in the answer of Darwin, 

 as a supplementary amendment is sometimes 

 made a part of the motion, still divides the 

 biological world into two camps. But in that 

 controversy between the Weismannians and 

 the Neo-Lamarckians, aptly called "The Battle 

 of the Darwinians," no matter what becomes 

 of the Lamarckian factor, all are agreed that 

 the "Natural Selection" of Darwin is impreg- 

 nable. 



Lamarck's theory may be summed up as 

 follows — 



(i.) Every change in the environment of 

 animals creates for them new needs.
