May 26, Genetic Cuckoo rated it really liked it Shelves: Similarly, the genes that make up a genotype are not selected for their harmonious interaction.
But by far the most gripping part comes from his title: Richrd a multitude of examples Dawkins demonstrates that ther An extra read for those who liked “The Selfish Gene”. Sep 25, Anatoly v01 rated it really liked it Shelves: Instead, at each locus, the alleles that are best able to propagate themselves via their modifications of the expressed phenotype, given their fellow genes, will be selected for. The mosquitoes are significantly more attracted to human breath and odours than uninfected mosquitoes.
Your two perspectives can be shifted between without many problems at all.
It’s great reading for everyone ready to grind through complexities of material. Reading some of the other reviews of the book, it seems to strike many readers as difficult reading. It’s an expansion of topics covered in The Selfish Gene, which I’d previously enjoyed, but there was too much detail for me to take in. In doing fehotipo, Dawkins never strays from his central themes: The idea is that the phenotypic effects of genes have no reason to stop at the boundaries of the specific individual.

Dawkins summarizes these ideas in what he terms the Central Theorem of the Extended Phenotype:. Want to Read saving…. Many parts of the book will likely give non-biologists like myself a headache, but it’s a good read for laymen nonetheless. The book promotes concepts called replicators genes, DNA and vehicles organisms, groups, species The key difference is that the balance is not driven by a push towards harmony but the ruthless interactions and pushes for self-replication between a myriad of different genes.
The chapters which are good are really, really good.
It’s almost worthwhile reading Dennett’s brief essay before starting Dawkins. Dawkins is a contemporary genius with fresh perspectives in several fields. In such cases, the manipulator can be said to have genes “for” the tichard of the manipulated organism that serves the manipulators reproductive interests. Feb 28, Svetlana rated it it was amazing. Another example of such behaviour is seen in female mosquitoes carrying richad parasites.
Directed at actual biologists. The last four chapters explain the long-reach-of-the-gene idea and argue that the phenotypical effects are not limited to one organism. Technically challanging for non-biologists. Using the gene’s eye view of life that he developed so well in The Selfish Genehe shows that animal artifacts are better understood as objects engineered by natural selection, rather than as by products rifhard the behavior of organisms. Despite of this the whole reading experience is very satisfying.
Dawkins effectively argues that this perspective will help clarify biologists thinking about Darwinian adaptation. Dawkins’s theoretical paradigm in this work, much like in The Selfish Geneintegrates heavily the thought and contributions of all the most important scientists of the modern synthesis, including William Hamilton, E.
He even dawkis with an optimistic view of life, presumably addressing the sadness? While this is a book starting its fourth decade, it still feels very fresh and eye-opening.
That’s not a challenge or a chore, it’s a pleasure. The rabbit runs faster than the fox, because the rabbit is running for his life while the fox is only running for his dinner. View all 3 comments. Dawkind one was written for biologists but the glossary in the end of the book and Dawkins’ illuminating prose make it easy to follow.
Genetic determinism, group selection, green beards etc. It is equally implausible that salamanders on the West side of North America should need many times more DNA than congeneric salamanders on the East side. I was able to understand in detail how evolution has operated throughout the ages. The way Extdndido takes a point to its ultimate conclusion, the way he manages to go beyond the point at which any other person would sit satisfied is amazing. The first chapters are aimed at precluding any possible misunderstandings of what Dawkins meant in “The Selfish Gene”.
Of course, this new approach revolves around the ide In The Extended PhenotypeRichard Dawkins proposes that the expression of a gene is not limited simply to the organism’s physical appearance or phenotype, that is the direct synthesis of proteins, or to the organism’s behaviour, but ricjard includes the impact of the phenotype and the behaviour on the organism’s environment.
Dawkins concise language is without rkchard in the biological sciences. Dawkins points out that animal adwkins and ultimately animal behaviour, may be advantageous not to the animal itself, but, for instance, to a parasite which afflicts it — “parasite manipulation”.
I’m sure this is great, but I’m not a scientist and as one of Dawkins least accessible books, this one was overkill. An animal’s behaviour tends to maximize the survival of the genes “for” that behaviour, whether or not those genes rivhard to be in the body of the particular animal performing it.
The Extended Phenotype: The Long Reach of the Gene
It raises an unanswered question: An animal’s behavior tends to maximize the survival of the genes ‘for’ that behavior, whether or not those genes happen to be in the body of the particular animal performing it. It extsndido like a laid back thesis, but is substantiated by multiple references and delivered with the refined technique of the experienced professor.
Quotes from The Extended Phen Dawkins is too defensive of his exyendido than necessary; the title of this book should ideally be “The Extended Phenotypeand Miscellaneous Topics and Debates in Evolutionary Biology. Views Read Edit View history.
