The third and most important main branch of primæval Malays, the curly-haired races, or Euplocomi, have probably left in the Dravidas of Hindostan and Ceylon, that species of man which differs least from the common primary form of the Euplocomi. The principal portion of the latter, namely, the Mediterranean species, migrated from their primæval home (Hindostan?) westwards, and peopled the shores of the Mediterranean, south-western Asia, north Africa, and Europe. The Nubians, in the north-east of Africa, must perhaps be regarded as an offshoot of the primæval Semitic tribes, who migrated far across central Africa almost to the western shores. The various branches of the Indo-Germanic race have deviated furthest from the common primary form of ape-like men. During classic antiquity and the middle ages, the Romanic branch (the Græco-Italo-Keltic group), one of the two main branches of the Indo-Germanic species, outstripped all other branches in the career of civilization, but at present the same position is occupied by the Germanic. Its chief representatives are the English and Germans, who are in the present age laying the foundation for a new period of higher mental development, in the recognition and completion of the theory of descent. The recognition of the theory of development and the monistic philosophy based upon it, forms the best criterion for the degree of man’s mental development. SYSTEMATIC SURVEY OF THE TWELVE HUMAN SPECIES. N.B.—Column A denotes the Average Number of the Population in millions. Column B shows the Degree of the Phyletic Development of the Species, thus Pr = Progressive Diffusion; Co = Comparative Stability; Re = Retrogression and Extinction. Column C denotes the Character of the Primæval Language; Mn (Monoglottonic) signifies that the Species had one Simple Primæval Language; Pl (Polyglottonic) a Compound Primæval Language. ----------------------+--------------------+--------+-------+--------+----------------------------- _Tribe._ | _Human | A. | B. | C. | _Home._ | Species._ | | | | ----------------------+--------------------+--------+-------+--------+-----------------------------
