Your two perspectives can be shifted between without many problems at all. Almost all of these criticisms are no longer pertinent which shows how correct Dawkins was at the time, might I addso some arguments seem a little trivial. To view it, click here.

This book was written circa 35 years ago. Sep 25, Anatoly v01 rated it really liked it Shelves: Dawkins, unlike other science writers, is forthright in declaring his advocacy in writing this book. Sometimes hard to understand. The Making of a ScientistBlack Swan,page By using this site, you agree to the Terms of Use and Privacy Policy. Genes exert a phenotypic effect, but this isn’t limited to the physical body of the organism; genes also affects behavior.

The general point here is that for an animal on one side of the arms race the penalty of failure is more severe than for fenitipo animal on the other side of the arms race. Feb 28, Svetlana rated it it was amazing. Apr 14, Katja rated it it was rjchard Shelves: It isn’t predictable, inevitable or reasonable. The last four chapters explain the long-reach-of-the-gene idea and argue that the phenotypical effects are not limited to one organism.

Although he delivers his narration as if sitting with you in a quiet study, you may still need to review his words more than o The essentials of life’s story: It would be a gift to readers beyond measure if these two ever collaborated on a book.

Another example of such behaviour is seen in female mosquitoes carrying malaria parasites. Variation gives life its grandeur, and Richard Dawkins gives us a description of the workings of variation.

The Extended Phenotype: The Long Reach of the Gene

Dennett’s capabilities in logical argument are superbly expressed here. Alternatively, the summary of the extended phenotype theorem that Dawkins provides in the recent editions of The Selfish Gene might be a good option. Do its conclusions still conform with results since collected? I’m sure this is great, but I’m not a scientist and as one of Dawkins least accessible books, this one was overkill. Oct 01, Molly Brodak rated it it was amazing.

Manipulation is but one way that an organism can benefit another’s genes, and it was interesting to learn about the different ways this occurs in nature. Of course, this new approach revolves around the idea that the gene is the fundamental unit of life in the organism, and that natural selection does not operate on the organism, or the population, or even the species, but on the gene itself; a concept introduced in The Selfish Gene.

In this book, Dawkins picks up his selfish gene theme and extends its influence to organs and systems within the body and then to the external environment. He points to the arbitrariness of restricting the idea of the phenotype to apply only to the phenotypic expression of an organism’s genes in its own body.

With a multitude of examples Dawkins demonstrates that there is no real reason to believe in “gene A of X accounts for X’s skin color” and at the same time deny anything like “gene A of X account’s for change in Y’s behavior”.

Dawkins argues that the only thing that genes control directly is the synthesis of proteins. Rather, given that every other organism already exists, a certain organism will have its various genotypes selected for or against depending on how their expressed phenotypes allow them to be ruthless exploiters and reproducers.

Dawkins develops this idea by pointing to the effect that a gene may have on an organism’s environment through that organism’s behaviour. View all 4 comments. This has to be the most objective work by Dawkins that I’ve read so far.

The technical extensido of the distinction between the organism s and the components to which are said to benefit from ‘phenotypic effects’ was cause for re-reading many paragraphs. No other writer cuts through conceptual confusion caused by verbal ambiguity like Dawkins.

Fenottipo is terrific at scientific reasoning, and this was a good outing from him, even by his standards. Thankfully because he summarizes his points at the end of each paragraph, even if one is clueless to the specifics of what he’s staying, it’s still possible to walk away with a confident grasp on how Natural Selection and Adaptive Fitness works.

It explains how the peacock extdndido it’s tail and the interesting train of between being desirable as a mate and being able to survive. Part of Dawkins presentation here reiterates that there is no “why” to either the process of evolution nor its results. I don’t Dawkins beyond succeeds in pursuing the task implied by the title of the book and the topic of his first best seller: Genetic determinism, group selection, green beards etc.

May 26, Genetic Cuckoo rated it really liked it Shelves: This influential and controversial book illuminates the complex world of genetics in an engaging, lively manner. This argument on the surface appears similar to what Jean Piaget puts forward in his book, Behavior and Evolution.

While this is a book starting its fourth decade, it still feels very fresh and eye-opening. Dawkins is a contemporary genius with fresh perspectives in several fields. 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 also includes the impact of the phenotype and the behaviour on the organism’s environment.

For instance, Venus Fly Traps possess genes for increasing the chances that denotipo will “choose” to fly into their traps. An animal’s behavior tends daqkins 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.
