WHO WILL IT BE?

The mystery of evolution is presented in this Italian import.

Constructed essentially in two parts, this richly illustrated picture book begins with a spare, poetic portrayal of the development of a vertebrate embryo from conception to birth. The text gracefully and sure-handedly leads readers to the startling fact that developing vertebrate embryos, whether fish, toad, snake, duck, fox, or human, all look alike, and for a time, it is impossible to tell what—or who—the embryo will become. This fascinating fact, presented artistically and subtly in the first part of the book, raises a desire for more information—which is obligingly supplied by the second part of the story. Here, the text leaves behind spare poetry and turns to more fact-filled information. A key evolutionary theory of Darwin’s—that all vertebrates are descended from a single ancestor and have evolved to adapt to survive particular climates—is presented in an easily understandable way while also underscoring the fascinating conclusion that all creatures are connected through evolution: a satisfying circling back to the earlier part of the book. Bossù’s illustrations both soothe and stimulate with colorful, soft-edged circles and amorphous shapes on pure-white backgrounds, imbuing richness and anticipation to the theme of evolution.

Richly illustrated and both poetically and informatively written.
