The Evolution of Calpurnia Tate by Jacqueline Kelley

It is 1899, just before the turn of the century. And while other girls Calpurnia's age are learning manners, sewing, and how to be proper girls, Calpurnia is far more interested in naturalism. Along with her grandfather, Calpurnia observes, collects, and studies insects, plants, and animals. She learns about Charles Darwin and the idea of natural selection.
