Ction is sort of like saying Super Bowl via playoffs #It may outline the process of competition and elimination but it doesn t tell you anything about the strategy that # may outline the process of competition and elimination but it doesn t tell you anything about the strategy that the team to the Super Bowl It only diverts your attention away from all the interesting detailsWhat is just now coming to the surface arguably 20 years late is the immensely sophisticated systems that drive evolutionary change as discovered by people like Carl Woese Lynn
and Barbara story focuses on the late Carl Woese in fact it s very nearly a full biography of the man So why should anyone care about Carl Woese And why should anyone even give consideration to the suggestion that he was as great a scientist as DarwinThe answer is that Woese flipped Darwin s tree of life 90 degrees in 1977 Any time someone introduces that large of a conceptual revolution to a field that person is a titan Woese showed that inheritance is a vast interconnected web and that Darwin s cherished tree metaphor has not minor but major failingsWoese showed that Horizontal Gene Transfer large sections of DNA being transferred wholesale from viruses and bacteria to other bacteria and plants and animals is a major component of evolution and in fact the history of life cannot be properly nderstood at all without itThis is as big of a deal to biology as antum mechanics was to Newtonian physics It transforms the speed of evolution from millions of years to in some cases hours and minutesIt shows that organisms find very clever ways to incorporate very large chunks of code obtained from elsewhere into their physiology Who knew that a large stretch of code stolen from a retrovirus was sed to build the human placentaIt changes genetics It changes disease treatment It changes genetic engineering and informs our se of gene editing technologies like CRISPR It changes the whole history of evolution and alters the very definition of inheritance It even raises deep estions about how purposeful and directional evolutionary systems actually areAt the end of the bookmargulis and barbara

And important; we now know that roughly eight percent of the human genome arrived sideways by viral infectiona type of HGT In The Tangled Tree the grandest tale in biologyDavid ammen presents the scienceand the scientists involvedwith patience candor and flair Nature We learn about the major players such as Carl Woese the most important little known biologist of the twentieth century; Lynn Margulis the notorious maverick whose wild ideas about mosaic creatures proved to be true; and Tsutomu Wantanabe who discovered that the scourge of antibiotic resistant bacteria is a direct result of horizontal gene transfer. I wanted to read the science of the
evolution of and how horizontal gene transferof life and how horizontal gene transfer Well there was some but there was the people who contributed to the science I skipped some pages because I just did not want to know that a retired scientist I had never heard of ate a pizza with nothing hot in it I advised a friend not to bother with the book I would have given a lower star rating but some people might want the biography I am tempted to give this three star but since the biographical research is so good I m giving it four I
