Though scientists do their best to classify all of the world’s countless living things into carefully organized species, hybrid animals can’t be described so easily. As the offspring of two different species, these creatures are neither one nor the other. Readers will learn about hybrids that occur naturally in the wild, such as the liger (half lion, half tiger), and those that have been created intentionally by human breeders, such as the Labradoodle (half Labrador retriever, half poodle). They will also explore the ethical and environmental issues surrounding hybrids.
