In Assembling Life, David Deamer addresses questions that are the cutting edge of
research on the origin of life. For instance, how did non-living organic compounds
assemble into the first forms of primitive cellular life? What was the source of those
compounds and the energy that produced the first nucleic acids? Did life begin in
the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars?
The book provides an overview of conditions on the early Earth four billion years
ago and explains why fresh water hot springs are a plausible alternative to salty
seawater as a site where life can begin. Deamer describes his studies of organic compounds
that were likely to be available in the prebiotic environment and the volcanic conditions
that can drive chemical evolution toward the origin of life. The book is not exclusively
Earth-centric, but instead considers whether life could begin elsewhere in our solar
system. Deamer does not propose how life did begin, because we can never know that
with certainty. Instead, his goal is to understand how life can begin on any habitable
planet, with Earth so far being the only known example -- Provided by publisher
