One of this century's leading evolutionary biologists, Motoo Kimura, revolutionized the field with his random drift theory of molecular evolution - the neutral theory - and his groundbreaking theoretical work in population genetics. This volume collects 57 of Kimura's most important papers and covers 40 years of his diverse and original contributions to our understanding of how genetic variation affects evolutionary change. Kimura's neutral theory, first presented in 1968, challenged the notion that natural selection was the sole directive force in evolution. Arguing that mutations and random drift account for variations at the level of DNA and amino acids, Kimura advanced a theory of evolutionary change that was strongly challenged at first and that eventually earned the respect and interest of evolutionary biologists throughout the world. This volume includes the seminal papers on the neutral theory, as well as many others that cover such topics as population structure, variable selection intensity, the genetics of quantitative characters, inbreeding systems and reversibility of changes by random drift.Background essays by Naoyuki Takahata examine Kimura's work in relation to its effects and recent developments in each area.

From the moment it first began to contemplate the world, three questions have occupied the human mind: Where do we come from? What are we? Where are we going? Artists (notably Paul Gauguin), religious thinkers, philosophers, and most recently scientists have all searched for answers. Here, the authors describe how scientists decipher human origin from the record encrypted in the DNA and protein molecules. After explaining the nature of descent and the methods available for studying genealogical relationships, they summarize the information revealed by the molecular archives about the Tree of Life and our location on one of its branches. The knowledge thus gleaned allows them to draw conclusions about our identity, our place in the living world, our future, and the ethical implications of the changed perspective.
