title: Phylogeny and its clinical significance.
abstract: The creation of the universe, the origin of life, and the rise of the one celled organism to man are reviewed. The embryologic development of man recapitulates the entire phylogenesis. The evolution of the sense organs (ear and nose) and food and airway passages is discussed in detail. Finally, observations are made regarding phylogenetic development and its relation to human congenital malformations and other pathologic processes.
