Abstract
Life on earth emerged around 4 billion years ago and its complexity has been increasing ever since. This book seeks to explore the conditions under which natural selection [3] would favour some of the key mechanisms by which those increases in complexity have come about, using simple models of evolution on abstract fitness landscapes. Wright [11] was perhaps the first to view natural evolution as a process of adaptation through a multidimensional space of fitness peaks and troughs (Fig. 1.1, top). Turing [10] would later highlight the potential universality of that view when considering ways to design intelligent computers: evolution as a general search process. Whilst no simple correlation between the amount of DNA in a given organism and its perceived complexity exists—lilies have more DNA than humans, for example—it is clear that the two are interrelated. Five ways in which an increase in the amount of DNA may occur are explored here.
