[PDF] The Tangled Tree: A Radical New History of Life AUTHOR David Quammen
David Quammen Þ 9 free downloadThis is an unusual one for uammen in that it features far less travel and getting out in the field which you may or may not miss It contains his trademark levity and enjoyment of a good scientific shit storm but doesn t have uite the same focus that his better works have Song of the Dodo remains his genre bending masterpiece and Outbreak the epitome of what a good opular science book should be It was still enjoyable but I got the feeling that uammen never uite found the over arching narrative that would give the book the shape it needed and I spent a substantial Gaddafis Harem period of time thinking that he was trying very hard to avoid mentioning Dawkins Selfish Gene which for all Dawkins later idiocies didrovide a useful reminder that selection happens on many levels and which starts to unpick some of the claimed inconsistencies of horizontal gene transferThis review I m not new to uammen s work His Song of the Dodo is to me one of the great masterpieces of modern science writing and as a writer myself uammen s work is a standard to which I hope I will only one day meet It goes without saying then that I came to The Tangled Tree with high expectations and I am leased to say they have been exceeded The book is a fascinating and compelling account
Of Our Understanding Ofour understanding of tree of life and as the title suggests how this is much complicated and tangled than we might initially have expected In short the book tells the story of molecular hylogenetics which is a new way of reading along and tracing the tree of life It shows for instance that a sizeable Laid to Ruin (Lancelots Fall, percentage of the human genome comes not from traditional inheritance but sideways through infection by virusesFor many I imagine this book might be a disappointment orleasant surprise unlike many typical science books uammen elects to tell his science through the lives of the scientists who made the discoveries in uestion In many
ways the book is as much a book on the history of science as it is on thethe book is as much a book on the history of science as it is on the itself Personally and as someone who has training in both biology and in the history of science I love this Leyendas Negras particular angle uammen takes but others might value a straightforward approach That said the book is highly readable full of surprising facts and superbly written I recommend this book highly to anyone interested in life genetics and the history of one of science s important developments in recent years Five stars Clearly author David uammen has done considerable research for this book and he intends to share all the details with you If you are interested in a book that tells you he met scientist Mike Gray at a Turkish restaurant the details of Ernst Haeckel s marriage and so on then this book is for you These stories do bring out the humanity of the individuals involved However I was expecting a book with this title to be much about the new views on life and evolution that have come up over the last few decadesarticularly around horizontal gene transfer HGT and the implications for human evolutionTo be fair he does cover uite a bit of the and his explanations are usually very clear although thi am tempted to give this three star but since the biographical research is so good I m giving it four I was drawn in to read this book because of the blurb which insinuated that I would be told of recent work taking us back to LUCAThis is really a book around two main themes a man Carl Woese and a field of study Horizontal Gene Transfer It gives very little technical detai lbut is The Iron Palace (Shadowed Path, primarily interested in theeople involved and goes backwards and forwards in time until you ve almost lost track of what the oint of it all was But the biographic. In this New York Times bestseller and longlist nominee for the National Book Award our greatest living chronicler of the natural world The New York Times David uammen explains how recent discoveries in molecular biology affect our understanding of evolution and lifes history In the mid 1970s scientists began using DNA seuences to reexamine the history of all life Perhaps the most startling discovery to come out of this new fieldthe study of lifes diversity and relatedness at the molecular levelis horizontal gene transfer HGT or the movement of genes across species lines It turns out that HGT has been widespread. .
Al details of the many many the bad boys of butte people involved is interesting and I did get the main thrust which is that Horizontal Gene Transfer is important However it was unclear at the end as to how important this is to evolutionary theory ie is is 90% or 10% I suspect the answer is we just don t know i wonder if it relates to the ideas ofunctuated euilibria that Steven Jay Gould used to support What exactly is Richard Dawkins Romancing the Customer position on it all At the moment it seems there is a lot still unknown Some will criticize this book because of its subtitle makes a bold claim A radical new history of life A reviewer in the Wall Street Journal for example was a little grumpy and tookains to reiterate that Darwin s theory of natural selection safely remains the central The Articles of Release (The Release pillar of biology thank you very muchWell OK but saying evolution by natural selection is sort of like saying Super Bowl vialayoffs It may outline the rocess of competition and elimination but it doesn t tell you anything about the strategy that got the team to the Super Bowl It only diverts your attention away from all the interesting detailsWhat

Ammen takes us on a historical tour of the fascinating scientists who uietly turned evolutionary theory sideways and upside down Carl Woese was resentful of Darwin and thought himself to be a superior scientist uammen himself doesn resentful of Darwin and thought himself to be a superior scientist uammen himself doesn go that far but there s a strong case to be made that
