Contents

In the preface, Fisher considers some general points, including that there must be an understanding of natural selection
Natural selection
Natural selection is the nonrandom process by which biologic traits become either more or less common in a population as a function of differential reproduction of their bearers. It is a key mechanism of evolution....

Evolution
Evolution is any change across successive generations in the heritable characteristics of biological populations. Evolutionary processes give rise to diversity at every level of biological organisation, including species, individual organisms and molecules such as DNA and proteins.Life on Earth...

) now allowed this. In the first chapter, Fisher considers the nature of inheritance, rejecting blending inheritance
Blending inheritance
Many biologists and other academics held to the idea of blending inheritance during the 19th century, prior to the discovery of genetics. Blending inheritance was merely a widespread hypothetical model, rather than a formalized scientific theory , in...

. The third considers the evolution of dominance
Evolution of dominance
The evolution of dominance concerns the evolution of genetic dominance. The central argument, that modifier genes act upon other genes to make them dominant or recessive, and that these are then themselves subject to natural selection was first proposed by the British population geneticist Ronald...

, which Fisher believed was strongly influenced by modifiers. The last five chapters (8-12) include Fisher's more idiosyncratic views on eugenics
Eugenics
Eugenics is the "applied science or the bio-social movement which advocates the use of practices aimed at improving the genetic composition of a population", usually referring to human populations. The origins of the concept of eugenics began with certain interpretations of Mendelian inheritance,...

 course and, through the time I spent on it, I think it notched down my degree. Most chapters took me weeks, some months.
...And little modified even by molecular genetics, Fisher's logic and ideas still underpin most of the ever broadening paths by which Darwinism continues its invasion of human thought.

Unlike in 1958, natural selection has become part of the syllabus of our intellectual life and the topic is certainly included in every decent course in biology.

For a book that I rate only second in importance in evolution theory to Darwin's Origin (this as joined with its supplement Of Man), and also rate as undoubtedly one of the greatest books of the twentieth century the appearance of a variorum edition is a major event...

By the time of my ultimate graduation, will I have understood all that is true in this book and will I get a First? I doubt it. In some ways some of us have overtaken Fisher; in many, however, this brilliant, daring man is still far in front.
