Description

The wondrous true story of one tiny bubble that sparked all life on Earth—including yours

Meet LUCA—our Last Universal Common Ancestor, the itty-bitty organism that every unique life-form on Earth can be traced back to. This sprinkle-sized blob was formed from the dust of exploded stars, water, and a lot of heat. LUCA was a single cell that split into two, and these cells multiplied into more organisms that grew and changed. Over the billions of years that followed, the descendants of LUCA evolved into bacteria, mushrooms, sharks, fir trees, lions—and humans! All the extraordinary life on Earth began with LUCA, through a miraculous process that could also occur on other planets.

This vibrant and poetic informational picture book breaks down scientific concepts using simple, engaging language. Striking illustrations bring LUCA to life and reveal how readers are connected to one another, and every life-form on our planet, through one tiny bubble.

About the authors

Karen Krossing grew up in Thornhill, Ontario, with a family who loved to read. What could she do but read, too? Karen began to create stories when she was eight, and she continued this habit by writing poetry in high school. By then she was hooked on books, so she studied English at university then became a book editor and a technical writer. After Karen had kids, she began writing fiction for children and teens.

Karen uses writing to understand the world around her. In Take The Stairs, which was nominated for the Ontario Library Association White Pine Award, she writes about turning adversity into opportunity through the troubled lives of inner-city teens. In Pure, her latest novel, she explores sticky ethical questions about genetic engineering that today's teens will have to face in their lifetimes.

Karen is a writing instructor at Centennial College and she teaches an after-school writing program for kids and teens through Pegasus Studios in Toronto. She led workshops at the 2003 Canadian Children's Book Camp in Toronto and was on tour with TD Canadian Children's Book Week in 2005. Karen regularly conducts writing workshops and book talks at Canadian schools.
