  Aleksandr Oparin Summary
Oparin was born near Moscow, the youngest child of Ivan Dmitrievich Oparin and Aleksandra Aleksandrovna.
Oparin's biochemical research on plant enzymes and their role in plant metabolism, important for its practical application, would also be important for what was to be the focus of his career, the question of how life first appeared on earth.

  Aleksandr Oparin - Wikipedia, the free encyclopedia
Aleksandr Ivanovich Oparin (Алекса́ндр Ива́нович Опарин, March 2 (February 18 Julian) 1894 – April 21, 1980) was a Soviet biologist and biochemist, who has been acclaimed as one of the greatest authorities on the origin of life.
Oparin sometimes was called "Darwin of the 20th century", and this is no exaggeration.
Oparin suggested that different types of coacervates might have formed in the Earth's primordial ocean and, subsequently, been subject to a selection process leading eventually to life.

Aleksandr Ivanovich Oparin (Алекса́ндр Ива́нович Опарин, March 2 (February 18 Julian) 1894 –; April 21, 1980) was a Soviet biologist and biochemist.
In his opinion, these were the raw materials for the evolution of life: At first there were the simple solutions of organic substances, the behavior of which was governed by the properties of their component atoms and the arrangement of those atoms in the molecular structure.
Oparin suggested that different types of coacervates might have formed in the Earth's primordial ocean and, subsequently, been subject to a selection process leading eventually to life.

Alexander Ivanovich Oparin () (– April 21, 1980) was a Soviet biologist and biochemist, who has been acclaimed as one of the greatest authorities on the origin of life.
Oparin became Hero of Socialist Labour in 1969, received the Lenin Prize in 1974 and was awarded the Lomonosov Gold Medal in 1979 "for outstanding achievements in biochemistry".
Oparin sometimes is called "Darwin of the 20th century." Although he began by reviewing the various panspermia theories, he was primarily interested in how life initially began.

Oparin states in his book Genesis and Evolutionary Development of Life: "Materialism, based on facts derived from natural science, confirms that life, like all the rest of the world, is material in nature, and it does not need for its understanding any sort of spiritual origin incomprehensible by experimental means.
During the precellular prebiological period first considered by A. Oparin and theoretically analyzed by M. Eigen, spontaneous mutations were the main cause of structural changes of information-containing molecules that increased their ‘selection value.’ Gradually, the increasing sophistication of the self-instrumental process led to supermolecular structures and finally to their most perfect combination - the cell.
Oparin’s hypothesis has become a theoretical stimulation all over the world for experimental modeling of life’s origin; this research is one of the main trends in modern biology." (1974:387).

La pequeña obra de Oparin tuvo una difusión muy limitada debido a que su edición se realizó sólo en ruso.
Para Oparin, los primeros sistemas vivos se habrían formado espontáneamente en el medio ambiente terrestre primitivo, gracias a una sucesión de procesos químicos y físico-químicos, procesos llamados prebióticos, de complejidad creciente.
Los coacervatos de Oparin (aunque obtenidos con materiales biológicos) o, sobre todo, las microesferas de Fox, formadas a partir de sus proteinoides, son ejemplos concluyentes de la formación prebiótica de esas microestructuras.

 Mathematical Philosophy and Evolution
Oparin makes the following all conclusive statement: "Engels shows that a consistent materialistic philosophy can follow only a single path in the attempt to solve the problem of the origin of life.
Indeed, the eminent Harlow Shapley stated in 1961 in the forward to Oparin's book "Life in the Universe" [3] that the sudden appearance of life forms is "irrational" [4].
In summary, those evolutionists who adhere to the philosophy of Oparin erroneously assume that there is only one general type of model for evolution that is acceptable scientifically.
