 includes Neanderthal man as no more than a subspecies. Space short- 

 age precludes further discussion of this topic save only to say that 

 in this scheme "Telanthropus" becomes H. erectus. For this reason 

 the genus Telanthropus (originally created by Broom and me in 1949) 

 was simk (Robinson, 1961) . 



This scheme reduces the contents of the whole family Hominidae 

 to three genera only: Paranthropus., Australopithecus, and Homo. 

 But it should be clearly recognized that these genera are not of the 

 same sort or of equal magnitude. Paranthropus and Australopithe- 

 c^is are validly distinct on any gromids. They were divergent, adap- 

 tively well separated stocks which represented an adaptive radiation 

 within the prehominines and could have occupied the same territory
