OUR FAMILY TREE

Luminous, eye-filling paintings accompany a poetic disquisition on our ancestors, from primordial single-celled creatures to dexterous, big-brained walkers. Framing the discourse with scenes of an adult drawing linked pictures in the sand for two children, Stringer (Mud, 2001, etc.) gives her dramatically posed prehistoric figures even more visual impact by outlining them in light, and placing them against vivid, undulant sea- or landscapes. Beginning with the appearance of multi-celled organisms, Peters (Cold Little Duck, Duck, Duck, 2000, etc.) traces successive developmental watersheds, including the appearance of backbones, lungs, warm blood, milk, and finally hands, through two major mass extinctions and up the present—then appends more detailed recapitulations of each stage in glosses and a separate time line. Source notes from author and illustrator cap a lyrical, carefully researched look into our deep past that will give young readers a firm sense of their place within the long history of life on this planet.
