An easy-to-read, overview of Darwin's life.
I'm not going to nit-pick details, but I do have a few comments about accessibility. Assuming the target audience is young adults, too many names are mentioned but not woven into the storyline (e.g., members of the Wedgewood family, Sym Convington). Mentioning works better in material for readers with prior knowledge than it does in an introduction.
But, more seriously, I doubt if the reader would come away with an understanding of natural selection based on this story alone. e.g,
p 85: ... the plants would slowly evolve in order to meet the challenges of the new environment.
I'll wager that the reader would envision particular plants 'adapting' to the new environment. Slowly? Well, it might take a couple of months. The time required for the kinds of changes Darwin is addressing is not explained clearly.
On p 91, there is a better example, but even it falls short.
In Origin, he led the reader step-by-step through the stages of natural selection, using the struggle for survival to show how a species could change over many generations in ways that enabled it to meet the challenges of its environment.
"Many generations" ... could that be four generations? five?
This book's a keeper.
