Synopsis

Charles Darwin wrote in The Origin of Species that "... unless profitable variations do occur, natural selection can do nothing." As Darwin recognised, natural selection, far from increasing variation within species, reduces variation constantly in favour of an optimum type. What then is the true source of variation in evolutionary systems? It is a question which has obsessed Warwick Collins, a novelist who had studied biology at university, for much of his adult life.

He proposed in March 2000 that the required degree of variation could be achieved if large numbers of inert or silent genes existed within the genome. Such genes, because they do not code for physical characteristics, could freely mutate over time without deleteriously affecting the host organism. At a later stage they could be switched on, by largely random processes, and generate exotic new variants. Remarkably, his description of silent genes was found to correspond precisely with the so-called junk genes. These are found in all species, forming the great majority of genes in multicellular species and rising to 98.5% of the genome in humans. Until then their function had proved mysterious.

In addition, Collins's theory predicted a number of features of the silent or junk genes which have since been increasingly verified by recent research: for example, that they could become active and begin to code and that they influenced other genes. It is now widely accepted that, just as Collins predicted, the vast majority of significant mutation in the genomes of complex species arises from the silent genes. But Collins's powerful and ambitious theory moves well beyond the molecular realm. He argues that while natural selection is a major force in evolution, it is primarily negative and entropic. Instead, the great driver of complex evolution is the range of variation created by the silent genes. As Professor Donald Braben writes in his illuminating foreword, "Collins is proposing a general evolutionary theory which, if it continues to be supported by the data, may in due course come to rival Darwin's theory that evolution is driven by natural selection."

Review

Two distinguished scientists encouraged Warwick Collins in writing his revolutionary theory of evolution. Professor Freeman Dyson, one of the world's leading theoretical physicists, wrote, "I like your theory, and think it has a good chance of being right." He added, "Darwin would have liked your theory." Professor Donald Braben, a nuclear physicist who directed a series of wide-ranging research programmes at BP, responded, "Hierarchically speaking, variation is of greater significance than selection. I agree, therefore, that if silent gene theory were proved correct, it would be the more complete theory, as Einstein's is compared with Newton's." --Donald Braben

Norman Thomas di Giovanni, the writer and celebrated translator of Borges, commented, "To a layman, the central arguments are utterly convincing. I wonder whether this book, with its beautiful dark horse of a cover, won't become the non-fiction surprise of the year." --N T di Giovanni

Christopher Hawkins, the economist and former MP, wrote, "This book should be read by everyone who is interested in the origin of our species." --Christopher Hawkins
