For you fans of abiogenesis research, SteveF at TalkRational noticed this tasty bowl of primordial boulliabaise at PLoS One, which I'm just sampling now:
| Quote | Emergence of a Code in the Polymerization of Amino Acids along RNA Templates
Abstract
"The origin of the genetic code in the context of an RNA world is a major problem in the field of biophysical chemistry. In this paper, we describe how the polymerization of amino acids along RNA templates can be affected by the properties of both molecules.
Considering a system without enzymes, in which the tRNAs (the translation adaptors) are not loaded selectively with amino acids, we show that an elementary translation governed by a Michaelis-Menten type of kinetics can follow different polymerization regimes: random polymerization, homopolymerization and coded polymerization.
The regime under which the system is running is set by the relative concentrations of the amino acids and the kinetic constants involved. We point out that the coding regime can naturally occur under prebiotic conditions. It generates partially coded proteins through a mechanism which is remarkably robust against non-specific interactions (mismatches) between the adaptors and the RNA template.
Features of the genetic code support the existence of this early translation system."

ETA: I'll go along with "The Screwtape Letters" as "classic," however derivative of Twain's "Letters From The Earth."
For me, the Narnia stuff and the "Space Trilogy" are mediocre and awful, respectively.
