Evidences of Man’s Advancement in Prehistoric Ages
From human remains, weapons, tools and other vestiges of human activity, found in the more recent deposits on the earth’s surface, the presence of man in these far off ages is made increasingly certain. The Pleistocene or Quaternary epoch, as represented by these objects of primitive culture, ranged over a vast period of time which has been conveniently divided into two great epochs, the Paleolithic or Old Stone, and the Neolithic or New Stone Age, these being so named from the material chiefly used by primitive peoples in the manufacture of their weapons and other implements. The distinction between the two periods, which are not to be taken as chronological, since they overlap in many places, is based essentially on the different treatment of the material, which during the immeasurably longer Old Stone Age was at first merely chipped, flaked, or otherwise rudely fashioned, but in the New more carefully worked and polished.
