Human Stem History Or Phylogeny PDF Download

Excerpt from The Evolution of Man, Vol. 2: A Popular Scientific Study; Human Stem-History or Phylogeny Hence each of the sedimentary strata has its characteristic fossils, the remains of the animals and plants that lived during that particular period of the earth's history. \vhen we make a comparative study of these strata, we can survey the whole series of such periods. All geologists are now agreed that we can demonstrate a definite historical suc cession in the strata, and that the lowest of them were deposited in very remote, and the uppermost in comparatively recent, times. However, there is no part of the earth where we find the series of strata in its entirety, or even approxi mately complete. The succession of strata and of corres ponding historical periods generally given in geology is an ideal construction, formed by piecing together the various partial discoveries of the succession of strata that have been made at different points of the earth's surface (cf.
