FINDS EELATING TO EAELY MAN

main groups, namely: (1) Baked earth, or tierra cocida; (2) scoriae; 

 (3) used or worked stones; and (4) used or worked bones. 



On the basis of these and the above-enumerated human specimens, 

 coupled with the presence in South America of certain small fossil 

 monkeys, Ameghino advanced the theory that mankind evolved on 

 that continent, that it was represented there in the course of time 

 by a number of genera of intermediary beings and by several species 

 of man himself, and that he spread thence over the rest of the world. 

 This elaborate theory can be given in this report only brief space; 

 for the many details which it involves it will be necessary to consult 

 Ameghino's original publications (see Bibhography) . The following 

 table, from Ameghino's Le Diprothomo Platensis (1909, p. 206), shows 

 the views of that author as to the sequence of the evolution, though 

 later his conceptions on that subject were probably even further 

 developed.
