First edition, first printing of this significant work by one of the founders of modern genetics.
Early in his career Morgan was, like many turn-of-the-century biologists, critical of both Darwin's theory of evolution by natural selection and Mendelian genetics. In 1904, hoping to prove a competing theory, he joined the faculty of Columbia University and began studying fruit fly heredity. By analysing the types and combinations of mutations that appeared in the flies, Morgan found that genes were specific to certain chromosomes, along which they were arranged linearly. This was a key discovery that laid the foundation for all of modern genetics, helped reaffirm Darwinism, and earned Morgan the Nobel Prize in 1933. The present volume contains a series of lectures describing contemporary controversies in evolutionary biology, the evidence for natural selection and Mendelianism, and the specifics of Morgan's own groundbreaking work on mutations and the chromosome.
