A delightful graphic novel, in which Charles Darwin himself explains the rudiments of deep time, common ancestry, and natural selection to Mara, a winsome befreckled adolescent who just happens to live in Darwin's left eyebrow — she is, after all, a follicle mite. Reviewing The Sandwalk Adventures for BioScience, NCSE deputy director Glenn Branch praised it for its "engaging art and snappy dialogue" as well as its pedagogical sophistication: "Hosler obviously is aware of the likely misconceptions that his readership will have about evolution." Also the author/illustrator of the equally delightful Clan Apis, a graphic novel about honeybees, Hosler teaches biology at Juniata College.
