Four Billion Years in One Book
Life: The First Four Billion Years takes on the full sweep of life’s history on Earth, from the earliest single-celled organisms through to the diversity of species alive today. Martin Jenkins turns a vast, complicated story into something young readers can follow chapter by chapter.
Science Writing Rooted in Fieldwork
Jenkins studied at Cambridge University before spending roughly a decade as a conservation biologist, work he’s described as taking him everywhere from investigating the chameleon trade in Madagascar to timber detective work in Kenya, experience that shows up throughout his nonfiction.
A Book Built Like a Timeline
Life: The First Four Billion Years is a large-format book, roughly 11.5 by 14 inches, organized chronologically by geologic era, from the Precambrian through the rise of humans. Illustrator Grahame Baker-Smith mixes narrative scenes with labeled scientific diagrams, fossils, and a running timeline, and the book closes with a glossary for the terms it introduces along the way. It’s pitched older than most of Jenkins’s picture books, closer to grades 5 through 8, giving it room to go deeper into the science than a younger-reader format would allow.
Where It Fits in Jenkins’s Work
Published by Candlewick Studio, it’s one of the more ambitious entries in Jenkins’s catalogue, trading the tight focus of a single-animal book for the full sweep of life on Earth. The scientific grounding is the same as his other titles, built on his years as a conservation biologist, but the scale and reading level make it a natural next step for a reader who has worked through his shorter books first.
