From fish to mammals and plants to insects, every organism on Earth must reproduce, and the survival of each species-and of life itself-depends on this and on the diversity it creates. In this groundbreaking book, Katherine Roy distills the science of reproduction into its simplest components: organisms must meet, merge their DNA, and grow new individuals; and she thoughtfully highlights the astonishing variety of this process with examples from across the natural world, from plants to insects to fish, birds, mammals, and more.

Lucid, informed, and illuminated by beautiful paintings, Making More weaves a story that seamlessly explains life's most fundamental process, answers children's questions, and provides an essential tool for parents, caregivers, and educators.
