Life and the Riddle of Randomness

Life and the Riddle of Randomness

(p.1) Chapter 1 Life and the Riddle of Randomness
Randomness in Evolution

John Tyler Bonner

Princeton University Press

This chapter first discusses the concept of randomness and its role in evolution. Unlike natural selection which carves out novelties that lead to evolution, randomness seems to go nowhere; it just shuffles things backwards and forwards. While there is some truth to this way of putting the matter, it is fundamentally wrong. This book focuses on variations in morphology, specifically eukaryotes, whose cells contain a nucleus and come in a great variety of shapes. Those vast numbers of varieties involve both unicellular and multicellular forms. The remainder of the chapter deals with role of chance in evolution, size and randomness, and sex. An overview of the subsequent chapters is also presented.

Keywords:   evolutionary biology, biological randomness, morphology, eurkaryotes, natural selection, evolution, size, sex
