Graceful, succinct prose and engaging illustrations trace the
evolution of life on Earth out of the blue and back again.
Clear and inviting nonfiction prose, vetted by scientists--together with
lively illustrations and a time line--narrate how life on Earth emerged
"out of the blue." It began in the vast, empty sea when 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.
