When Fish Got Feet, Sharks Got Teeth, and Bugs Beg pdf epub mobi txt 电子书 下载 2024
Written in a lively, conversational style and illustrated with the author's colourful, scientifically accurate paintings and very funny cartoons, When "Fish Got Feet, Sharks Got Teeth, and Bugs Began to Swarm" takes readers back 430 million years ago - long before dinosaurs existed - to a time when life on land was limited to tiny bugs crawling around under equally tiny plants. Over the next 80 million years or so, four-legged creatures made their first appearance on Earth, as "fish got feet." Age-appropriate appendixes, including a time line of life on Earth and a chart to help keep vertebrates straight, make this an excellent curriculum support resource.
