James Trefil, Harold Morowitz, and Eric Smith in American Scientist:
In this article we present a view gaining attention in the origin-of-life community that takes the question out of the hatchery and places it squarely in the realm of accessible, plausible chemistry. As we see it, the early steps on the way to life are an inevitable, incremental result of the operation of the laws of chemistry and physics operating under the conditions that existed on the early Earth, a result that can be understood in terms of known (or at least knowable) laws of nature. As such, the early stages in the emergence of life are no more surprising, no more accidental, than water flowing downhill.
The new approach requires that we adopt new ways of looking at two important fields of science. As we will see below, we will have to adjust our view of both cellular biochemistry and thermodynamics. Before we talk about these new ideas, however, it will be useful to place them in context by outlining a little of the history of research on the origin of life.
