The Tangled Tree
- A Radical New History of Life
- By: David Quammen
- Narrated by: Jacques Roy
- Length: 13 hrs and 48 mins
In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.
Quammen at his usual best

One of the Best of 2018 Science Books
I thoroughly enjoyed this book and was sorry when I came to the end. The Tangled Tree explains the current thinking in evolutionary theory in terms that are understandable by anyone, even those without a background in biology. Horizontal gene transfer is the most exciting discovery in the field since Darwin. David Quammen has done an excellent job of describing the history of evolutionary theory to date as well as humanizing the scientists involved. Highly recommended!
