An Introduction to Astrobiology

Summary: More astro than biology
Review: This is an excellent textbook, with straightforward problems ... and answers! There's plenty of solid material here and very little fluff. The information is well presented, up-to-date, and easy to read.

Three of the nine chapters are about the potential for life elsewhere in our planetary system, in particular on Mars, Europa, and Titan. Another three chapters are on extrasolar planets: how to find them, what we've discovered so far about them, and what signatures of life we might try to look for on them in the future. There's also a chapter on the search for extraterrestrial intelligence (SETI). That leaves two chapters for the definition and origin of life, the Earth's acquisition of the necessary water and carbon, and so on. I'd prefer to see quite a bit more on biology here. I'd like to see much more discussion of the development of multicellular life, the changes in the Earth's environment caused by the production of oxygen, and the evolution of humans.

That said, I really liked the chapter on the origin of life. It was illuminating to read about the origin of chirality, written by a specialist in organic matter in meteorites. And I also especially liked the chapters on exoplanets.
