Biological Molecules 
of biological atoms, certain molecules, can only 
exist in conjunction with certain other combina- 
tions. This is quite in accordance with the 
teaching of physiologists regarding the inter- 
dependence of the various organs of the body. 
We have now reached the stage of the fertilised 
ovum. According to our conception it is a series 
or conglomeration of the precursors of the unit 
characters of the adult. These precursors we 
call biological molecules. Each is of a very com- 
plex nature. Each seems to be composed of 
several portions, only one of which will take 
part in the building up of the body of the off- 
spring, the other portions remaining latent. We 
further conceive that it is possible for the various 
radicles which compose these molecules to ar- 
range themselves in various manners, and with 
each new arrangement a different form of unit 
character will be developed. These molecules, 
then, are built up from radicles derived from 
both parents, the most stable combinations being 
formed and one portion of the molecule domin- 
ating the whole. Under normal circumstances 
this dominant portion of the molecule will give 
rise to a character of a definite type. But it 
seems that other factors may come into play and 
cause a rearrangement of the radicles which 
compose it, and this will result in the formation 
of a unit character different from that to which it 
would ordinarily give rise.
