Lamarckism or tin- Lamarckian Theory. The doi 

 trine based upon the teachings of the French naturalist, 

 J. B. P. A. de Monet de Lamarck (i 744-1829), who 

 attempted to explain the progressive evolution of nature 

 by virtue of an inherent tendency to development 

 through the appetency and habits of living organisms, 

 the efforts excited by change of conditions reacting 

 upon the structure. It is based on the theory that 

 matter acted upon by heat, light, and electricity may 

 spontaneously generate life of " low, homogeneous 

 organisms, and that such organisms would develop 

 qualities of heterogeneity and organs as governed by 

 their surroundings, and especially by their wants or 

 desires. To this preponderating influence of new 

 wants Lamarck ascribes the chief role in evolution, 

 while Darwin emphasizes the advantage of acciden- 

 tal variations in the struggle for existence. See Neo- 

 lamarckism.
