    Straight leg bones. Awkwardly contorted arm bones. On a hot summer day in 2005, Dr. Douglas Owsley of the Smithsonian Institution peered into an excavated grave, carefully examining the fragile skeleton that had been buried there for four hundred years. He was about fifteen years old when he died. And he was European, Owsley concluded. But how did he know? Just as forensic scientists use their knowledge of human remains to help solve crimes, they use similar skills to solve the mysteries of the long-ago past. Join author Sally M. Walker as she works alongside the scientists investigating colonial-era graves near Jamestown, Virginia, as well as other sites in Maryland. As you follow their investigations, she'll introduce you to what scientists believe are the lives of a teenage boy, a ship's captain, an indentured servant, a colonial official and his family, and an enslaved African girl. All are reaching beyond the grave to tell us their stories, which are written in bone.

    But scientists started to challenge that idea and in 1859 Charles Darwin, a naturalist and biologist, wrote a famous book called On the Origin of Species that revolutionised the way that we have understood evolution ever since.Now molecular biologist and illustrator Sabina Radeva has recreated Darwin's most famous work as a beautifully illustrated book. The stunning pictures bring the theory of evolution to life for young readers, and anyone who wants to learn about evolution.Pulling together Darwin's observations from his travels around the world and his ground-breaking explanation of how species form, develop, and change over hundreds of thousands of years, On The Origin of Species is as relevant and important now as it ever was.A very important project, most beautifully realised.
