How do living things come to fit their surroundings so well? Morgan examines the theory of evolution and the explanations offered for adaptation: Darwin’s artificial, natural and sexual selection, and the inheritance of acquired characters. He tests each against the evidence of experiment, and he is notably sceptical of selection as the whole answer.
An early work by the future Nobel laureate of fruit-fly genetics, showing how unsettled evolutionary theory still was in 1903. Download the free EPUB.
