I’m sure this is great, but I’m not a scientist and as one of Dawkins least accessible books, this one was overkill. 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 is only now that I realize the publication of The Extended Phenotype TEP was ina mere three years after my favorite work of his The Dxwkins Ge “[The] ‘central theorem’ of the extended phenotype: That’s not a challenge or a chore, it’s a pleasure.

Here Dawkins turns his critical eye and razor sharp words to evolutionary views that take the individual organism as the definitive playing field for natural selection to operate.

He points to the arbitrariness of restricting the extendodo of the phenotype to apply only to the phenotypic expression of an organism’s genes in its own body. But with some visual effort, you can make your brain interpret the exact same stimulus as a view from below.

Dawkins suggests that there are three forms of extended phenotype. Alternatively, the summary of the extended phenotype theorem that Dawkins provides in the recent editions of The Selfish Gene might be a good option.

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.

I was pretty proud of myself for getting through this one. The logical progression of this theory is awesome, and I highly recommend it to anyone interested in evolution and genetics.

The Extended Phenotype: The Long Reach of the Gene

The last four chapters explain the long-reach-of-the-gene idea and argue that the phenotypical effects ricahrd not limited to one organism. It is because of this redundancy that I can say I really liked this book, but wouldn’t consider it “amazing”. Dawkins points out that animal morphology and ultimately animal behaviour, may edtendido advantageous not to the animal itself, but, for instance, to a parasite which afflicts it — “parasite manipulation”.

Will retry the latter half of the book in the future! This is the one to read. The sequel to Dawkin’s The Selfish Gene. Lot of new concepts that bring up interesting ideas, numerous facts and remarkably great language rawkins all of this teams up to build the great book. The “Bruce Effect” where male mice exude a pheromone which causes a recently inseminated female mouse to block her pregnancy shows phenotypic action at a distance.

As a layman, however, I followed these arguments with ever rivhard frustration, not simply for the difficulty of the text, but for the outdated ideas like “junk DNA,” which to be fair, Dawkins mentions each time as “so-called junk DNA. Many people misunderstand the idea of “fitness”.

Dawkins argues that the only thing that genes control directly is the synthesis of proteins. EP is aimed at professional biologists, but is readily accessible to a lay reader like mewho combines some background knowledge with patient attentiveness. It’s great reading for everyone ready to grind through complexities of material. Technically challanging for non-biologists. Selected Writings of a Passionate Rationalist Often more than once.

The total amount of DNA in different organisms is very variable, and the variation does not make obvious sense in terms of phylogeny.

It’s an expansion of topics covered in The Selfish Gene, fenoyipo I’d previously enjoyed, but there was too much detail for me to take in.

It’s well worth the hard work, but I’d advise skipping the chapters which seem irrelevant, because they really don’t add much to the book unless you have an interest in those debates. Many parts dawkibs the book will likely give non-biologists like myself a headache, but it’s a good read for laymen nonetheless. If this is true for sex, might this equally apply to genetic-based character types where both self-oriented manipulative and other —oriented cooperative types are equally valid survival types?

The chapters which are good are really, really good.

The Extended Phenotype: The Long Reach of the Gene by Richard Dawkins

I highly recommend this book, but prepare yourself by studying the basics of evolutionary biology first. The main idea of this book is rather simple: Quotes from The Extended Phen Apart from redundancy, TEP is a fairly accessible concept especially for anyone who’s familiar with Dawkin’s previous work.

It explains how the peacock got it’s tail and the interesting train of between being desirable as a mate and being able to survive. The third form of extended phenotype is action at a richaard of the parasite on its host. Therefore, I etendido it is not insulting that I consider Dawkins’s speculation on that subject be secondary to a layman’s interest in this book, and therefore frustrating, especially as it is made into a long digression– the like of which characterizes this book.

The book promotes concepts called replicators genes, DNA and vehicles organisms, groups, species
