Overview

From the first signs of life in the Precambrian Period to the end of the Cambrian Period about 488 million years ago, Early Life explores one of the most extraordinary periods in the evolution of life on Earth. Characterized as a "biological big bang," the Cambrian Period was a relatively short span of time during which nearly all basic forms of animal life that still exist first appear in the fossil record of Earth's ancient oceans. Alien-looking marine creatures developed in the oceans, and the first predators began hunting down other species in a biological "arms race" that pitted elegant strategies for defense against increasingly efficient means of attack. Early Life draws from the latest research to tell the compelling story of Earth's earliest organisms and their enormous importance to our understanding of the other forms of life that have evolved since.
