Synthesized answer
The author surveys many experiments using new molecular techniques. These experiments have revealed the enormous wealth of hereditary variation among individuals and have quantified the genetic changes that occur in the origin of new species [1].
However, the passages do not detail the specific evidence provided by these experiments. They state that a satisfactory explanation for the origin and maintenance of such variation is still lacking [1], and that current population genetic theory appears inadequate to cope with the data [1]. The author also urges the development of theory that considers the evolution of the genome as a whole, rather than independent gene evolution [1, 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…
