A fascinating, comprehensive, accessible account of conodont fossils—one of paleontology's greatest mysteries. Simon J. Knell takes the listener on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

The current view of science is that Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life on Earth, and then the first single-celled life-forms, early bacteria and algae, began to emerge. It’s unknown where they came from or even if they originated on this planet at all, but this gradual development continued until suddenly (in relative geological terms), more complex forms of life began to emerge.
