Szostak's protocells are built from fatty molecules that can trap bits of nucleic acids that contain the source code for replication. Combined with a process that harnesses external energy from the sun or chemical reactions, they could form a self-replicating, evolving system that satisfies the conditions of life, but isn't anything like life on earth now, but might represent life as it began or could exist elsewhere in the universe.
"A stunning survey of the latest evidence for intelligent life on Mars. Mac Tonnies brings a thoughtful, balanced and highly accessible approach to one of the most fascinating enigmas of our time."
--Herbie Brennan, author of Martian Genesis and The Atlantis Enigma
"Tonnies drops all predetermined opinions about Mars, and asks us to do the same."
--Greg Bishop, author of Project Beta

--David Jinks, author of The Monkey and the Tetrahredron
"Mac Tonnies goes where NASA fears to tread and he goes first class."
--Peter Gersten, former Director of Citizens Against UFO Secrecy
