For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now.

It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?: The Quest for Cosmic Life (Basic Books, 2024), the veil is finally lifting. The authors describe how life's building blocks--from RNA to amino acids and cells--could have emerged from the chaos of Earth's early existence. They then apply the knowledge gathered from cutting-edge research across the sciences to the search for life in the cosmos: both life as we know it and life as we don't.

Why and where life exists are two of the biggest unsolved problems in science. Is Earth Exceptional? is the ultimate exploration of the question of whether life is a freak accident or a chemical imperative.
