larities and especially of parallelisms. In the light of these data and the 

 theory of V. A. Dogiel^we came to the conclusions about the necessity for 

 more careful attention to the questions of the oriented (directed, nobis) 

 development which is clearly observed in nature and can be fully explained 

 from positions of dialectical materialism (sic,? nobis). 



All the general questions touched upon in the present work can- 

 not be solved through the materials of the study of one group of animals 

 (alone, nobis ). They demand wide research in a number of groups^ and can 

 be solved more or less successfully only in this manner. We hope that in 

 the future we will be able to return, be it only to certain of the general 

 questions which were touched upon in the present work.
