具体描述
This book dives deep into the past when life first began. From the plant-like goo that brought oxygen to Earth to the lumbering "gorgonopsids" from which all mammals evolved, the book explores over 3500 million years of strange creatures and how humans have learned about them. Readers will marvel at the scary-looking creatures from the pre-Dinosaur era: spiders the size of manhole covers, giant sea-scorpions as big as bicycles.
