Richard Dawkins: How a scientist changed the way we think Edited by Alan Grafen and Matt Ridley

If Darwin's revelation of natural selection is "the best idea anyone, any where, ever had", then Richard Dawkins' identification of the "selfish gene" must run a close second. While Darwin's concept explained the workings of life, Dawkins' insight disclosed the mechanism of natural selection. The 1976 publication of "The Selfish Gene" not only stimulated a fresh wave of thinking among biologists, it also stirred public interest and imagination. If life was under the thrall of those strings of chemicals in our cells, how far did that influence reach? In this set of excellent essays on the issues, Dawkins ideas and their impact are presented and discussed. The fruit of his insights are bittersweet, and while most of these writings applaud his probity and communication skills, there is the tang of doubt about some of them.

More than two dozen essays comprise this collection. They are topically organised, starting with the biology issues, moving through the logic Dawkins uses to his writing skills. Today, the biology seems straightforward: genes build bodies. Those bodies contain nervous systems and brains - the root of behaviours. At the publication of "The Selfish Gene", it was widely thought that evolution worked at the species' level. Dawkins moved that mechanism much deeper. Its effect is manifested through various ways, with mate choice one of the more significant. Andrew Read explains how evolutionary pressure forces such practices as "lekking" in certain bird species. The mechanism can be readily projected to other creatures, and is manifested in humans, as well.

Nature via Nurture- Matt Ridley

Following his highly praised and bestselling book Genome: The Autobiography of a Species in 23 Chapters, Matt Ridley has written a brilliant and profound book about the roots of human behavior. Nature via Nurture explores the complex and endlessly intriguing question of what makes us who we are.

In February 2001 it was announced that the human genome contains not 100,000 genes, as originally postulated, 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.

The Rational Optimist- Matt ridley

Life is getting better—and at an accelerating rate. Food availability, income, and life span are up; disease, child mortality, and violence are down — all across the globe. Though the world is far from perfect, necessities and luxuries alike are getting cheaper; population growth is slowing; Africa is following Asia out of poverty; the Internet, themobile phone, and container shipping are enriching people’s lives as never before. The pessimists who dominate public discourse insist that we will soon reach a turning point and things will start to get worse. But they have been saying this for two hundred years.


Yet Matt Ridley does more than describe how things are getting better. He explains why. Prosperity comes from everybody working for everybody else. The habit of exchange and specialization—which started more than 100,000 years ago—has created a collective brain that sets human living standards on a rising trend. The mutual dependence, trust, and sharing that result are causes for hope, not despair.

The meme machine

What is a meme? First coined by Richard Dawkins in his 1976 study The Selfish Gene, a meme is any idea, behavior, or skill that can be transferred from one person to another by imitation: stories, fashions, inventions, recipes, songs, and ways of plowing a field, throwing a baseball, or making a sculpture. It is also one of the most important--and controversial--concepts to emerge since Darwin's Origin of the Species. 

Here, Blackmore boldly asserts: "Just as the design of our bodies can be understood only in terms of natural selection, so the design of our minds can be understood only in terms of mimetic selection." Indeed, The Meme Machine shows that once our distant ancestors acquired the crucial ability to imitate, a second kind of natural selection began: a survival of the fittest among competing ideas and behaviors. Those that proved most adaptive--making tools, for example, or using language--survived and flourished, replicating themselves in as many minds as possible. These memes then passed themselves on from generation to generation by helping to ensure that the genes of those who acquired them also survived and reproduced.
