natural selection is the actuating cause of evolutionary progress 
lacks evidence of fact and force of logie“... .. „The causes of 
evolution are to be saught, not in the environment, but in the 
organization of species as groups of individually diverse, freely 
interbreeding organisms. The results of the evolutionary process, 
as shown in such groups as the millipeds, indicate that variations 
not only occur but become established in expression as new cha- 
racters without having any direct adaptive value for selection 
to work upon. ... .. Instead af evolution being limited to the 
adaptive characters that are fostered by selection there seems to 
be full liberty of change in all directions, that are not too harm- 
ful to the environmental interests of the species“. — ‚A new
