Origin of life means the appearance of simplest primordial life from non-living matter.
Evolution of life means the gradual formation of complex organisms from simpler ones. Chemosynthetic Theory of Origin of Life Several theories have been put forth to explain the origin of life. The widely accepted theory is the Chemosynthetic theory of origin of life, proposed by A.I. Oparin. Other. Evidences supporting biochemical origin of Life Publication of Oparin’s book created a kind of stir in scientific community and many thought that if life could originate naturally in oceans by simple biochemical reactions, it should be possible to produce it in laboratory by recreating the primitive atmosphere of earth.

He tried to understand the origin of life as part of the biochemical reactions’ evolution, by means of the Darwinian competition and selection, in the pre-biotic Earth (before the emergence of life).

09/10/ Origin of life 1. INTRODUCTION Several attempts have been made from time to time to explain the origin of life on earth. As a result, there are several theories which offer their own explanation on the possible mechanism of origin of life. Following are some of them: • Theory of Special Creation • Theory of Spontaneous Generation • Theory. This theory states, "Gradual transformation (transmutation) of inorganic compounds to organic compounds and organic compounds to proto cell (life) is called Biochemical origin of life.".
3. Redefining the problem: an algorithmic origin for life. By the above considerations, it seems that digital or analogue alone is insufficient to provide a satisfactory account of the origin of life—not just on technical grounds, but for deep conceptual reasons.
The former suffers from difficulties of prebiotic synthesis and due to Cited by: Life - Life - The origin of life: Perhaps the most fundamental and at the same time the least understood biological problem is the origin of life. It is central to many scientific and philosophical problems and to any consideration of extraterrestrial life.
Most of the hypotheses of the origin of life will fall into one of four categories: Hypothesis 1, the traditional contention of theology.

The concept of a biochemical origin of life was first proposed by Russian biochemist A.I. Oparin in and later supported by English scientist J.B.s Haldane in Thus, this theory is also called Oparin and Haldane theory. They believed the origin of life started along the origin and evolution of earth and atmosphere.

It is clear the that life came into existence from non living substances of primordial earth about 3 billion year ago. Origin of life can be explained by following theories: 1. Theory of special creation: Spanish monk Father Sudrez. According to this theory, all the living beings on earth were created by god or by some. 13/11/ The chemical origin of life is full of chicken-and-egg conundrums.
Among these is the origin of protein synthesis. Nature's protein-based enzyme catalysts are built from the polymerization of amino acids, yet this process itself requires enzymes, adenosine triphosphate (ATP), and, most often, a ribosome.

Biochemistry, study of the chemical substances and processes that occur in plants, animals, and microorganisms and of the changes they undergo during development and life. It deals with the chemistry of life, and as such it draws on the techniques of analytical, organic, and physical chemistry.
The first 'modern' model for the origin of life was presented in the s independently by two remarkable scientists, the Russian biochemist A. I. Oparin () and the British evolutionary biologist J. B. S. Haldane (). Oparin and Haldane share the distinction of being independent co-founders of the so-called biochemical theory for the origin of life, as well as being known. B iochemistry is the study of the chemical composition of the living matter and the biochemical processes that govern life activities throughout growth and maintenance .It comes from the words “bio” meaning “life” and chemistry, thus the “chemistry of life”.
Unlike other fields, it focuses on the processes that occur at molecular level by studying how the structure of a molecule. Origin-of-life theorists believe that the next step in the origin of life is that — entirely by chance — more and more complex molecules formed until some began to self-replicate. From there, they believe Darwinian natural selection took over, favoring those molecules which were better able to make copies.
Eventually, they assume, it became inevitable that these molecules would evolve. Biochemistry or biological chemistry, is the study of chemical processes within and relating to living organisms.
A sub-discipline of both biology and chemistry, biochemistry may be divided into three fields: structural biology, enzymology and hqzq.prodecoring.ru the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines.

In fact, their book was the “bestselling graduate-level text on the origin of life and established Kenyon as a leading researcher in the field.”  In the book, Kenyon and Steinman held that the origin of life was necessary based.
PDF; Abstract. The application of network science to biology has advanced our understanding of the metabolism of individual organisms and the organization of ecosystems but has scarcely been applied to life at a planetary scale. To characterize planetary-scale biochemistry, we constructed biochemical networks using a global database of 28, annotated genomes and metagenomes and
