Prof. Peter Klopfer and his daughter Erika Honoré have published a book for children about evolution. "Darwin and the First Grandfather" tells how young Tim becomes curious after seeing some family photos. Did his grandfather have a grandfather? What about his grandfather's grandfather's grandfather? His mother tells him no one knows for sure how people came to be, but Darwin had a theory. . . . The book is illustrated by Gretchen Morrissey.
