The Tangled Tree ~ by David Quammen

Brilliant book – Quammen tells us the story of what has been happening to the idea of the “Tree of Life” idea in the field of biology. Charles Darwin came up with that idea and a little graphic back in the early to mid-19th century and it stuck until now. (The idea wasn’t brand new to Darwin, though.).

But where Darwin’s tree had two basic branches (plants and animals) that idea was challenged in 1977 when, thanks to all the new techno-logy available, a 3rd form of life, a new kingdom, was discovered by Carl Woese. It was called archaeans, and following that, cells of this new form were found in other plants and animals. What did that do to the idea of separate plant and animal kingdoms? 

And with Darwin’s specialty being evolution. -what did it do to that idea? How did other scientists react? How did non-evolutionists react? What doors did it open? 

That all transpired back in 1977 and. a LOT has happened since then. Quammen covers it well. We don’t even have a tree anymore, not really. If one were to diagram what has been being found, it could look more like the “Tangled Tree” of the book’s title, but it really seems more like a web or a road map with intersections and all. 

This is a 2016 (metagenomic) representation of the tree of life[1] (from Wikipedia

Qammen writes very nicely and the book is wonderfully well organized. There are sections of biography on the important names, especially Woese, who, as a very old man, went out fighting for his own vision.

    • I’m sure it’s got to be “dumbed down” for students under high school college prep. I think they could start with Darwin’s tree and explain how over the last couple centuries technology has shown us more so scientists have found it to be a wee bit more complicated. “And yes, dear students, we’ll only be really studying the plant and animal kingdoms.” LOL –
