The Selfish Gene by Richard Dawkins

For these I took my inspiration from the two books in the field that have most excited me during the intervening years: Robert Axelrod's The Evolution of Cooperation, because it seems to offer some sort of hope for our future; and my own The Extended Phenotype because for me it dominated those years and because-for what that is worth- it is probably the finest thing I shall ever write. And if our species is not so exceptional as we might like to think, it is even more important that we should study the rule. Or it may be a class of entities, such as rain drops, that come into existence at a sufficiently high rate to deserve a collective name, even if any one of them is short-lived. He is also a committed atheist and an active critic of religion, to this end publishing his book The God Delusion and setting up the Richard Dawkins Foundation for Reason and Science. A gene that makes it possessors die is called a lethal gene.

The Selfish Gene Summary

To be sure, the metaphor gets it partly right: 'angles', unlike theories, cannot be judged by experiment; we cannot resort to our familiar criteria of verification and falsification. Jacques Monod made this point very well in his Herbert Spencer lecture, after wryly remarking: 'Another curious aspect of the theory of evolution is that everybody thinks he understands it! For me their insight had a visionary quality. Sometimes when atoms meet they link up together in chemical reaction to form molecules, which may be more or less stable. Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs, something that no other species has ever aspired to. I amusing the word gene to mean a genetic unit that is small enough to last for a large number of generations and to be distributed around in the form of many copies. But in our human estimates of what is probable and what is not, we are not used to dealing in hundreds of millions of years. This metaphor will take us quite a long way.

I am addicted to revising, and Marian Dawkins has been subjected to countless drafts and redrafts of every page. Instead, he described evolutionary processes as analogous to a blind watchmaker. If molecules of type X and type Y last the same length of time and replicate at the same rate, but A makes a mistake on average every tenth replication while Y makes a mistake only every hundredth replication, Y will obviously become more numerous. But by definition luck, good and bad, strikes at random, and a gene that is consistently on the losing side is not unlucky; it is a bad gene. This gene selfishness will usually give rise to selfishness in individual behaviour.

He was formerly Professor for Public Understanding of Science at Oxford and was a fellow of New College, Oxford. The people are suffering from color blindness, sugar, and many other diseases, they carry all these diseases in their genes. Perhaps one reason for the great appeal of the group- selection theory is that it is thoroughly in tune with the moral and political ideals that most of us share. We might expect that he would have qualities such as toughness, a quick trigger finger, and the ability to attract loyal friends. It touches every aspect of our social lives, our loving and hating, fighting and cooperating, giving and stealing, our greed and our generosity.

Instead - ten seconds of google search. A monkey is a machine that preserves genes up trees, a fish is a machine that preserves genes in the water; there is even a small worm that preserves genes in German beer mats. The things that we see around us, and which we think of as needing explanation-rocks, galaxies, ocean waves-are all, to a greater or lesser extent, stable patterns of atoms. That subject will always remain a distant dream according to Richard. The building blocks that attach themselves in this way will automatically be arranged in a sequence that mimics that of the replicator itself. The genes are not destroyed by crossing-over, they merely change partners and march on. Another theory, due to Sir Peter Medawar, is a good example of evolutionary thinking in terms of gene selection.

In exchange, aphids benefit from having strong fighters like the ants around to protect them. . Another rare kind of mistake or mutation which has important long-term consequences is called inversion. If only, like a greenfly, she would bud-off children who were exact replicas of herself, she would pass 100 per cent of her genes on to the next generation in the body of every child. They are visible under a microscope as long threads, and the genes are strung out along them in order. Richerson and Robert Boyd argue that only a Darwinian theory of cultural evolution can explain these unique characteristics. We do not know what chemical raw materials were abundant on earth before the coming of life, but among the plausible possibilities are water, carbon dioxide, methane, and ammonia: all simple compounds known to be present on at least some of the other planets in our solar system.

An individual body seems discrete enough while it lasts, but alas, how long is that? Humans depend on communication, yet this leaves us vulnerable to manipulation. It is not one of those books that was reviled as revolutionary when published, then steadily won converts until it ended up so orthodox that we now wonder what the fuss was about. The A contingent in the population loses not only the errant 'children' themselves, but also all their descendants, actual or potential. The organic substances became locally concentrated, perhaps in drying scum round the shores, or in tiny suspended droplets. But I have glossed over some complications and hidden assumptions.

I would write a book extolling the gene's-eye view of evolution. An efficient herbivore, on the other hand, needs flat grinding teeth, and a much longer intestine with a different kind of digestive chemistry. Every living thing looks for , to comprehend the intricacy of the evolutionary mechanism, you should add the idea of competition among species to the notion of replication that we mentioned. Even if there were, there is nothing sacred about definitions. My point was that there are two ways of looking at natural selection, the gene's angle and that of the individual. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think. So, one particular sperm cell might make up its Volume 1 by taking the first 65 pages from Volume la, and pages 66 to the end from Volume lb.

A person has blue eyes only if both copies of the relevant page are unanimous in recommending blue eyes. I now wonder why we don't censor most of our jargon from learned journals too. If genes really turn out to be totally irrelevant to the determination of modern human behaviour, if we really are unique among animals in this respect, it is, at the very least, still interesting to inquire about the rate to which we have so recently become the exception. Intelligent life on a planet comes of age when it first works out the reason for its own existence. This may have been how the first living cells appeared.

Different body features, behaviors, and even altruistic actions are nothing but tools for them. Here is a book that set a new standard in science writing for the wider public, a modern masterpiece that fresh generations of aspiring young scientists would seek to emulate. They are also subject to evolutionary change from within. This includes the mimics, and so genes for mimicry are favoured by natural selection. Populations may last a long while, but they are constantly blending with other populations and so losing their identity. Actually a molecule that makes copies of itself is not as difficult to imagine as it seems at first, and it only had to arise once.
