Pithecanthropos Erectus
The first race of Man (circa 550,000 B.c.) is called the "Pithecanthropos Erectus," or Ape Man. They were powerfully built individuals, with low foreheads, prominent bony ridges above the eyes, and retreating chins. Their forearms were heavy and clumsy, their thigh-bones bent and their shin-bones short, so they must have been bow-legged and awkward in gait. This type of human being became differentiated from animals because development of the faculty of primitive speech enabled them to sustain thought and created memory.
Eoanthropos
A second race of Subman, named " Eoanthropos " or " Dawn Man," was in existence (circa) 110,000 B.C. Their only weapons were branches torn from the trees
Cro Magnon
Circa 35,000-15,000 B.C. This date, 35,000 B.C., is given as the end of the Early Paleolithic Age and beginning of the Late Paleolithic Age. A fourth race, the Cro Magnon or " True Man " Type, lived during this period, and was akin to the Eskimo of the present day. These people occupied the cave-dwellings of their predecessors, but led a much freer life in the open.
Neolithic or New Stone Age Man
The Neolithic or New Stone Age: Circa 10,000 B.C. The people of this period constituted a fifth race of mankind, of moderate stature and slender proportions. Those who resided on the western side of the island now known as Great Britain were dark, and of the Iberian type. Those on the eastern side were fair, and very like the Gauls.
