Evolution and Genetics
Excerpt from Evolution and Genetics
HE third reprinting Of the Vanuxem Lectures for 1915-16, entitled A Critique of the Theory of Evolution, having been exhausted, the publishers have asked for a revised edition. The revision is no less an attempt at a critique Of the evolution theory than its predecessor, but, as the change in title sug gests, greater attention is here paid to one Of the most debated questions among evolutionists today, namely, the bearing Of the recent discoveries in genetics and in mutation on the theory Of evolution. While in a general way Darwin's theory Of Natu ral Selection is independent Of the origin Of the new variations that furnish it with its materials, yet the scientific formulation Of the theory is intimately con nected with the origin and inheritance Of suitable vari ations. For instance, if most of the observed variabil ity Of animals and plants were due directly to the environment, and if the effects thus brought about were not inherited, such variability could no longer be appealed to as material for natural selection. Again, if the variations that appear as mutants are always defective types, they could not, even though they are inherited, be appealed to as furnishing ma terial for progressive evolution.

About the author
Thomas Hunt Morgan
127 books6 followersThomas Hunt Morgan Ph.D. (Zoology, Johns Hopkins University, 1890) was an evolutionary biologist, geneticist, embryologist, and science author who won the Nobel Prize in Physiology or Medicine in 1933 for discoveries relating the role the chromosome plays in heredity.
Morgan researched embryology during his tenure at Bryn Mawr College, the sister school of his alma mater. Following the rediscovery of Mendelian inheritance in 1900, Morgan's research moved to the study of mutation in the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University, Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. He was the first person to be awarded the Nobel Prize in Physiology or Medicine for his work in genetics.
During his distinguished career, Morgan wrote 22 books and 370 scientific papers, and, as a result of his work, Drosophila became a major model organism in contemporary genetics. The Division of Biology he established at the California Institute of Technology has produced seven Nobel Prize winners.
