PRE-ORGANIC EVOLUTION 



tions. To do so, not only does not solve the problem, 

 but worse than that, places a road block in the path 

 of scientific investigation and leads human intelligence 

 into a blind alley. 



As the organic compounds that gave rise to living 

 structures could not have existed at the time the earth 

 began to solidify, they in turn must have developed 

 from simpler substances. It is consequently apparent, 

 that a "pre-organic" evolution of chemical complexity 

 must have preceded the evolution of life. Therefore in 

 order to gain a proper understanding of the path along 

 which living material has developed, one would do 

 well to begin the investigation of the evolution of non- 

 living matter as early in the history of the universe as 

 is possible. 



There is, of course, no certainty of the specific man- 

 ner in which the galaxies with their fantastically great 

 number of individual stars were formed. However 

 much available evidence leads to the view that the 

 galaxies condensed out of the extremely rarefied gas or 

 dust that at one time filled tremendous spaces, but was 

 in unstable equilibrium because of internal gravita- 

 tional forces or turbulence. . 



It is not necessary to discuss here whether this 

 process is one that may be going on continuously some- 

 where in space, or whether it took place only during 

 an earlier stage in the development of the universe. 

 Nor need one agree fully with this particular theory
