V. THE NATURE OF EVOLUTION 



protein molecule having synthesized as a replica corresponding to such 

 a template protein possessing the structure of a memory should have 

 the same structure of the memory, the memory or the training effect 

 can be "inherited". However, if the training is neglected, the side 

 chains, and ©, will gradually reappear, with the recovery of I- 

 structure, on account of the reversible character of the protein struc- 

 ture, thus occurring the oblivion of the memory.

The situation may be somewhat different with B-form; thus, when 

 the protein long stands without returning to A-form, under the en- 

 vironment which favours B-form the side chains will reappear but 

 not in the same arrangement as in I ; the arrangement occurs so as 

 to be favourable for the protein to take the B-form. As a consequence.
