The Dawn Races of Early Man

62:0.1About one mil­lion years ago the im­me­di­ate an­ces­tors of man­kind made their ap­pear­ance by three suc­ces­sive and sud­den mu­ta­tions stem­ming from early stock of the lemur type of pla­cen­tal mam­mal. The dom­i­nant fac­tors of these early lemurs were de­rived from the west­ern or later Amer­i­can group of the evolv­ing life plasm. But be­fore es­tab­lish­ing the di­rect line of hu­man an­ces­try, this strain was re­in­forced by con­tri­bu­tions from the cen­tral life im­plan­ta­tion evolved in Africa. The east­ern life group con­tributed lit­tle or noth­ing to the ac­tual pro­duc­tion of the hu­man species.
