Today we're speaking with Roland Ennos, author of The Age of Wood: Our Most Useful Material and the Construction of Civilization.

As the dominant species on Earth, humans have made astonishing progress since our ancestors came down from the trees. But how did the descendants of small primates manage to walk upright, become top predators, and populate the world? How were humans able to develop civilizations and produce a globalized economy? Now, in The Age of Wood, Roland Ennos shows for the first time that the key to our success has been our relationship with wood.

Roland Ennos is a visiting professor of biological sciences at the University of Hull. He is the author of successful textbooks on plants, biomechanics, and statistics, and his popular book Trees, published by the Natural History Museum, is now in its second edition. He lives in England.
