Living Fossils: Survivors from Earth's Distant Past

Life on Earth has existed for 3.5 billion years. In that time, 99.9 percent of the species that have ever lived have gone extinct. But a few have survived almost completely unchanged . . .

Take a journey through time to meet six living fossils: the chambered nautilus, the horseshoe crab, the platypus, the West African lungfish, the tuatara, and the solenodon. Author Rebecca E. Hirsch takes readers on an adventurous and comprehensive look at evolution, extinction, and a spectacular timeline of the history of animal life on Earth. Dive into the stories of these incredible animals and find out how they help scientists piece together evolutionary history.
