February, 2001, it was announced that the human genome contains not 100,000 genes, as originally expected, but only 30,000. This startling revision led some scientists to conclude that there are simply not enough human genes to account for all the different ways people behave; we must be made by nurture, not nature. Yet again biology was to be stretched on the Procrustean bed of the nature-nurture debate. Matt Ridley argues that the emerging truth is far more interesting than this myth. Nurture depends on genes, too, and genes need nurture. Genes not only predetermine the broad structure of the brain, they also absorb formative experiences, react to social cues, and even run memory. They are consequences as well as causes of the will.
Nature Via Nurture chronicles a revolution in our understanding of genes. Ridley recounts the hundred years' war between the partisans of nature and nurture to explain how this paradoxical creature, the human being, can be simultaneously free-willed and motivated by instinct and culture.
