  Origin of life - Facts, Information, and Encyclopedia Reference article
Several models reject the idea of the self-replication of a "naked-gene" and postulate the emergence of a primitive metabolism which could provide an environment for the later emergence of RNA replication.
One of the earliest incarnations of this idea was put forward in 1924 with Alexander Oparin's notion of primitive self-replicating vesicles which predated the discovery of the structure of DNA.
More recent variants in the 1980s and 1990s include Günter Wächtershäuser's iron-sulfur world theory and models introduced by Christian de Duve based on the chemistry of thioesters.

 INTRODUCTION: MORE THAN PANSPERMIA by Brig Klyce   (Site not responding. Last check: 2007-11-01)
But in the 1920s, Russian biochemist Alexander Oparin and English geneticist J.B.S. Haldane, writing independently, revived the doctrine of spontaneous generation in a more sophisticated form.
In the new version, the spontaneous generation of life no longer happens on Earth, takes too long to observe in a laboratory, and has left no clues about its occurrence.
That experiment is now famous, and the Oparin - Haldane paradigm still prevails today.

 SEP: Life
While not attracting the attention nor levels of funding of molecular biology, there was a continuous research program during much of the twentieth century on the origin of life (for historical summaries see Fry 2000; Lahav 1999).
During the 1920s Alexander Oparin and J.B.S. Haldane independently proposed the first modern hypotheses as to how life might have originated on earth (Oparin 1929/1936; Haldane 1929/1967).
In effect this type of approach can be termed a metabolism -first view.

 Troubled House - DARWIN'S THEORY   (Site not responding. Last check: 2007-11-01)
Such a proposal required a plausible mechanism explainable through natural processes.
Then, in the 1920s, Alexander Oparin and J.B.S. Haldane proposed a way that amino acids might have been produced in the early earth's "reducing" atmosphere.
Amino acids (put simply) are specifically shaped clumps of atoms.

 Harun Yahya - Articles - Scientific American's 15 Errors
Following all the speculation in the first six of his 15 questions, Rennie finally comes to an important matter in Question 7; The Origin of Life.
All that Rennie does in the face of that question is to sum up in a few sentences the scenario that evolutionists have been putting forward ever since the time of Alexander Oparin in the 1920s.
After admitting that "The origin of life remains very much a mystery," Rennie tries to make the scenario credible by saying, "...
