Agent Eagle is part of a group called the Eagle-Eyed Explorer Club. His mission is to file a report on the history of bugs. He learned that bugs evolved around 540 million years ago, during the Cambrian period. Most of those bugs were what we now call arthropods.
Bugs have many common characteristics such as exoskeletons, three body segments, antennae, and six legs. Many have compound eyes, which are a group of hexagonal panels that flicker with movement. That is why some bugs seem to sense movement immediately and fly away!
Bugs first evolved in the ocean but eventually crawled onto land. Scientists can study prehistoric bugs today because of trace fossils, or sometimes bugs were caught in a tree sap called amber. We can see exactly what they looked like millions of years ago!
One of my favorite things about this book is that it has a HUGE fold-out timeline about the history of bugs in the back of the book. I love all the details about specific bugs in the book, including the pictures of what scientists think some of the prehistoric bugs looked like. I love bugs, so I really enjoyed this book!
