30 THE HISTORY OF CREATION, 
CHAPTER XVI. 
PEDIGREE AND HISTORY OF THE KINGDOM OF THE 
PROTISTA. 
Special Mode of Carrying out the Theory of Descent in the Natural System 
of Organisms.—Construction of Pedigrees.—Descent of all Many- 
Celled from Single-Celled Organisms.—Descent of Cells from Monera.— 
Meaning of Organic Tribes, or Phyla.—Number of the Tribes in the 
Animal and Vegetable Kingdoms.—The Monophyletic Hypothesis of 
Descent, or the Hypothesis of one Common Progenitor, and the 
Polyphyletic Hypothesis of Descent, or the Hypothesis of Many 
Progenitors.—The Kingdom of Protista, or Primzyal Beings.—Eight 
Classes of the Protista Kingdom—Monera, Amcebe, or Protoplastze.— 
Whip-swimmers, or Flagellata.—Ciliated-balls, or Catallacta.—Labyrinth. 
streamers, or Labyrinthulez.— Flint-cells, or Diatomeze.—Mucons-moulds, 
or Myxomycetes.— Root-footers (Rhizopoda).—Remarks on the General 
Natural History of the Protista: Their Vital Phenomena, Chemical 
Composition, and Formation (Individuality and Fundamental Form).— 
Phylogeny of the Protista Kingdom. 
By a careful comparison of the individual and the palzeonto- 
logical development, as. also by the comparative anatomy 
of organisms, by the comparative examination of their 
fully developed structural characteristics, we arrive at 
the knowledge of the degrees of their different structural 
relationships. By this, however, we at the same time 
obtain an insight into their true blood relationship, which, 
according to the Theory of Descent, is the real reason of the 
structural relationship. Hence by collecting, comparing, and
