Many people enjoy an adventure story. Others like mysteries that lead the reader to an exciting discovery. The story of the young British naturalist Charles Darwin combines both of these. That is why the author and illustrator  Rosalyn Schanzer chose to write the children's book "What Darwin Saw". The book was published just in time for the 200th anniversary of Charles Darwin's birth on February 12, 1809. Rosalyn Schanzer carefully gathered Darwin's thoughts and observations from his diaries, letters and books. Many of the words in the book are Darwin's own. She also traveled to the Galapagos Islands and South America. She researched some of the places Darwin had visited on his trip on the ship, the Beagle in the 1830s. She took thousands of pictures, which helped her create the book's beautiful and color1ful drawings. These pictures show young readers what led Darwin to form his great discovery: the evolution of species through natural selection. "What Darwin Saw" tells of the adventures of a young man who traveled around the world as a scientist. The voyage of the Beagle took Charles Darwin to South America, where he rode horses with cowboys and met Native Americans in Argentina. He reported the eruption of the Osorno Volcano and experienced an earthquake in Chile. Darwin's observations showed him that environments can change very quickly and a great deal over time. Rosalyn Schanzer brings to life the clues that suggested to Darwin that living things evolve, or change, over time. She illustrates the unusual tortoises, birds and lizards that Darwin studied in the Galapagos Islands. She shows how Darwin came to understand that these island animals had differences, developed over time, that helped them survive. And she explains the theory of evolution through natural selection in a way that both children and adults will enjoy. Rosalyn Schanzer took thousands of pictures in order to   _  .
