All life as we know it is carbon-based, reliant on sources of liquid water and energy for its survival, and as far as we are aware, exists only on Earth.Our planet occupies a unique spot in the solar system. It is just the right distance from the Sun--within the so-called Goldilocks Zone--to be not too hot or too cold for liquid water to be stable on its surface, which, together with a protective shielding atmosphere, allowed the four-billion-year journey from a single-celled organism to an upright humanoid species. Most of primordial life, if seen today, would be classified as “alien,” as it bears little resemblance to anything that currently exists.We can learn much about the possibilities of extraterrestrial life by studying life forms from our planet's history and by exploring organisms still present in harsh environments on Earth that mimic those on other worlds. These organisms, called “extremophiles,” are directing our search for alien life throughout the solar system and beyond. Could we one day find Earth's toughest animal, the microscopic water bear, living under the surface of another world? Goldilocks and the Water Bears is an accessible introduction to the most fascinating of all the astro-sciences--the quest to learn whether we are alone in the universe.

Finally, science is catching up. This groundbreaking book unites the indigenous knowledge, the latest research, and the author's own experience of four decades in the field to lead us toward a deeper connection to the animals and, in the end, a deeper connection to ourselves.
