1. As relações entre a concepção de natureza de F. Engels e a hipótese A. I. Oparin sobre o problema da origem da vida na terra
The Russian biochemist Alexandre Ivanovicth Oparin , in 1924 in the former Soviet Union wrote an article in which he puts forward his hypothesis about a delicate subject in the history of biology: the origin of life on Earth. Proposes his hypothesis about th origin of life relating the biological evolution mainly the Natural Selection Theory of Charles Darwi

2. Da geração espontânea à química prebiótica
In the present paper, a historical view from spontaneous generation of life to Oparin-Haldane hypothesis was discussed. It was also showed what is the main concern of the field of prebiotic chemistry. Several aspects of prebiotic chemistry such as synthesis of biomolecules and biopolymers, primitive metabolism and genetic code, and the importance of the adso

3. Photoreduction of carbon dioxide by aqueous ferrous ion: An alternative to the strongly reducing atmosphere for the chemical origin of life
We have shown that ferrous ion at neutral pH photoreduces water to hydrogen with a high quantum yield on excitation with near-ultraviolet light. This simple system also efficiently reduces carbon dioxide (bicarbonate ions) to formaldehyde. Overall, these reactions offer a solution to a dilemma confronting the standard or Oparin-Urey model of the origin of li
