I am delighted to welcome back to Forthright Radio, award winning author, journalist, David Quammen. He was our guest 5 years ago after his book, SPILLOVER: Animal Infections and the Next Human Pandemic was published. His latest book, THE TANGLED TREE: A RADICAL NEW HISTORY OF LIFE, published by Simon & Schuster came out a couple of weeks ago. And lest you think this book, being about science – the research and theorizing – isn’t something you’d be interested in – let me tell you, this recent research reveals just how bacteria become resistant to our most potent antibiotics so quickly and fatally to so many, or how Horizontal Gene Transfer not only allowed for evolution, but may explain how certain cancers develop – as well as questioning our most basic concepts of ourselves as a species and individuals. And this puts a new meaning on “Tree Huggers” and “Tree Cutters”.
David Quammen has won many awards for his books and magazine articles, including from the National Association of Science Writers, and the Society of Biology (UK) Book Award in General Biology. His work with National Geographic is particularly noteworthy, and has taken him on myriad, lengthy difficult treks, which distinguish him from most authors, such as chronicling J. Michael Fay’s 2,000 mile survey hike through the forests of Central Africa, The Megatransect.
Charles Darwin speculated on the evolution of life as a tree, with “I think” written on top.
A popular 20th century version based on Darwin’s idea of a tree of evolution. At least this one, doesn’t place humans explicitly above other species.
In the 20th century there has been a tumultuous debate as to how best to characterize the concept of evolution. Is it a tree? Is it a web? Is it a net? A mosaic?
In David Quammen’s book, Carl Woese’s work was crucial to the debate, pioneering molecular phylogenetics, using (at the time) dangerous, innovative techniques to study RNA as a basis to determine species and evolution.
After demonstrating that there was a third “kingdom”, the Archaea, different from Bacteria, Carl Woese proposed a new Tree of Life pictured above.
LynnMargulis, married Carl Sagan when she was 19. After bearing 2 sons with him, she moved on. She took her second husband’s name, Margulis while making her revolutionary mark on biology. After juggling the three jobs of scientist, mother and wife, she decided to forego that last job, wife.
Her work synthesized earlier ideas, which she coined, endosymbiosis, that organelles, crucial to more complex life forms – including humans – were based on “infective heredity” by bacteria, that established essential organelles such as mitochondria, chloroplasts and centrioles.

Our guest today is veteran journalist, researcher and author, Carey Gillam, who has more than twenty-five years’ experience in the news industry covering corporate America. Since 1998, Carey Gillam’s work has focused on digging into the big business of food and agriculture. As a former senior correspondent for Reuters’ international news service, and a current contract researcher and freelance writer, she specializes in finding the story behind the spin — uncovering both the risks and rewards of the evolving new age of agriculture. Her areas of expertise include biotech crop technology, agrochemicals and pesticide product development, and the environmental impacts of American food production. She is currently Research Director for the nonprofit U.S. Right to Know. Her book, 
These are some of his articles cited in this interview:
Hard headed Louisiana fisherman Thomas Gonzales doesn’t know what will hit him next. After decades of hurricanes and oil spills he faces a new threat – hordes of monstrous 20 pound swamp rats. Known as “nutria”, these invasive South American rodents breed faster than the roving squads of hunters can control them. And with their orange teeth and voracious appetite they are eating up the coastal wetlands that protects Thomas and his town of Delacroix Island from hurricanes. But the people who have lived here for generations are not the type of folks who will give up without a fight. Thomas and a pack of lively bounty hunters are hellbent on saving Louisiana before it dissolves beneath their feet. It is man vs. rodent. May the best mammal win.
Jamie Redford embarks on a colorful personal journey into the dawn of the clean energy era as it creates jobs, turns profits, and makes communities stronger and healthier across the US. Unlikely entrepreneurs in communities from Georgetown, TX to Buffalo, NY reveal pioneering clean energy solutions while James’ discovery of how clean energy works, and what it means at a personal level, becomes the audiences’ discovery too.

These gabions are filled to the brim with rocks and go as far as 18 feet deep into the ground.
At first glance, they have the striking appearance of an intricate stone wall, a contrast to the border barrier just 100 yards away.
