The Three Coaches
Use these coaches to help you as you read.

Welcome to the true story of the evolution  of vertebrates.  This book tells about the major adaptations  that these animals evolved, in order.  For each adaptation, the scientific name of the new group of animals is given, and you can see a cladogram showing the story of evolution.

The three coaches are also here to help you.  Pedro will prompt you with questions to consider as you read.  Hali will give hints to help you answer these questions. Monty will model sample responses to the questions.  Please use the coaches to help you think deeply about the evolution of vertebrates.
