CHAPTER XXIV. 
ORIGIN AND PEDIGREE OF MAN. 
The Application of the Theory of Descent to Man.—Its Immense Importance 
and Logical Necessity.—Man’s Position in the Natural System of 
Animals, among Disco-placental Animals.—Incorrect Separation of 
the Bimana and Quadrumana.—Correct Separation of Semi-apes 
from Apes.—Man’s Position in the Order of Apes.—Narrow-nosed Apes 
(of the Old World) and Flat-nosed Apes (of America).—Difference of 
the two Groups.—Origin of Man from Narrow-nosed Apes.—Human 
Apes, or Anthropoides.—African Human Apes (Gorilla and Chimpanzee). 
—Asiatic Human Apes (Orang and Gibbon).—Comparison between the 
different Human Apes and the different Races of Men.—Survey of the 
Series of the Progenitors of Man.—Invertebrate Progenitors (Prochor. 
data) and Vertebrate Progenitors, 
OF all the individual questions answered by the Theory of 
Descent, of all the special inferences drawn from it, there is 
none of such importance as the application of this doctrine 
to Man himself’ As I remarked at the beginning of this 
treatise, the inexorable necessity of the strictest logic forces 
us to draw the special deductive conclusion from the general 
inductive law of the theory, that Man has developed 
gradually, and step by step, out of the lower Vertebrata, 
and more immediately out of Ape-like Mammals. That 
this doctrine is an inseparable part of the Theory of 
Descent, and hence also of the universal Theory of Develop- 
ment in general, is recognized by all thoughtful adherents
