The central thesis of "The Genetic Basis of Evolutionary Change" by Richard C. Lewontin is that current evolutionary theory is inadequate to explain the vast amount of hereditary variation observed. The author argues that population genetic theory leads to conflicting conclusions regarding the forces acting on this variation [Passage 2].
Lewontin emphasizes the crucial importance of gene interactions in evolution and proposes that new theories are needed. Specifically, he urges the development of theory that considers the evolution of the genome as a whole, rather than focusing on the independent evolution of individual genes [Passage 1, Passage 2]. The book surveys experiments revealing hereditary variation and quantifying genetic changes in species origin, and proposes new theories to address the challenges in understanding the origin and maintenance of this variation [Passage 2].

Title: The Genetic Basis of Evolutionary Change by Richard C. Lewontin Description: In this volume the author surveys the many experiments using new molecular techniques that have revealed the enormous wealth of hereditary variation among individuals and have quantified the genetic changes that take place in the origin of new species. Dr. Lewontin proposes new theories to attack the problems which still confront the scientist. While a tremendous amount of variation has been revealed, a satisfactory explanation of the origin and maintenance of such variation is still lacking. It is not at all…
