Out of the Blue

“Readers can begin to understand the joyous, wondrous, frightening complexity of the creation of life. A book to be read over and over for its intriguing story, illustrations, and captions.” —School Library Journal (starred review)

Clear and inviting nonfiction prose, vetted by scientists—together with lively illustrations and a time line—narrate how life on the Earth emerged “out of the blue.” It began in the vast, empty sea when the Earth was young. Single-celled microbes too small to see held the promise of all life-forms to come. Those microbes survived billions of years in restless seas until they began to change, to convert sunlight into energy, to produce oxygen until one day—Gulp!—one cell swallowed another and the race was on. Learn how and why creatures began to emerge from the deep—from the Cambrian Explosion to crustaceans, mollusks to fishes, giant reptiles to the rise of mammals—and how they compare to the animals we know today, in a lively and accessible outing into the prehistoric past that boils a complex subject down to its lyrical essence.

Standard and Primary covers are widely available through general retailers. They often have higher print runs and can be cheaper, especially during sales.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
