period in tlic lower Paleolithic. In many respects it approached nt'arertothe 

 type ol the modern race than eitherol t lie other two. This third ract'of the lower 

 Paleolithic is known as Eoanthropiis dawsoni, the i-'iltdown or dawn man. 

 His fossil remains w ere found in Sussex, England. By some he is regarded asthe 

 direct ancestor ot Homo sapiens, In others he is held to be an independent 

 branch ol the human lamily ol quite unknown relations to all other races. 



CHARACTERISTICS ESSENTIAL TO A COMMON PROGENITI\'E STOCK 



\\ ith Pithecanthropus, Heidelberg man, Eoanthropus, the Piltdow n and 

 Neanderthal man thus eliminated as the direct ancestors of the himian race as 

 it exists to-day, it must be admitted that e\ idcnce of a common progenitive 

 stock is entirely missing. Such a stock must ha\'e been much more generalized 

 in t\ [)e, resembling, lor example, some ol the more primitive extant races. 

 Perhaps it was not unlike the primiti\e Tasmanians, whose last surxiving 

 representatives passed away within the last hall century. Keith belie\es thatof 

 all the races ol mankind now alix'c, the aboriginals ot Australia aloiu- could 

 ser\e in such ancestral capacity. This common ancestor must needs produce 

 descendants which, on the one hand, might become the typical inhabitant 

 of central Africa and, on the other, the lair-haired native oi northwestern 

 Europe. The Australian aborigine has those intermediate and generalized 

 characters needed lor such an ancestral form. II it be agreed, therelore, that 

 he or some other primiti\e race ol like kind was the common ancestor ol the 

 \\ hite and black races, it is apparent that a long period ol exolution would be 

 necessar\ to product' such divergent descendants as the negro and the Euro- 

 pean. I'Or this reason, kt'ith beliexes that ihv |n'riod conct'rned in 

 this differentiation must ha\e \)vcn at least as long as the entire Pleistocene. 

 Indeed, this liardly seems sullicient lor the purpose. Such an estimation con- 

 sequently places the more |jrimiti\e forms of man, as Pithecanthropus, 

 further back than is usually conceded to be the case, it is kiith's opinion
