What is Origin of Life, part-2 (Introduction and Historical Development)

1. Super natural theory: All the different forms of life that occur today on planet are created by super natural power. It has no scientific basis.

2. Theory of Special Creation: According to this theory all the different forms of life on planet are created by God. Special creation theory believes that the things have not undergone any significant change since their creation. The theory of Special Creation was purely a religious concept, acceptable only on the basis of faith. This idea is found in the ancient scriptures of almost every religion.

The religious views are as follows:

Hindu mythology: Lord Brahma created the living world in one stroke.

Christian & Islam belief: God created this universe, plants, animals and human beings in about six days.

[• 3 main postulates: – All different kinds of animals & plants were created at once. – All organisms were created in the same form in which they exist today. – Their bodies & organs have been designed to fully meet the needs of the environment.]

Sikh mythology/concept: All forms of life including human beings came into being with a single word of God.

This theory has no scientific basis.

3. Theory of catastrophism: This is the modification of the theory of Special Creation. This theory was supported by French scientists Georges Cuvier and Orbigney. It states that there have been several creations of life by God, each preceded by a catastrophe resulting from some kind of geological disturbance. According to this theory, since each catastrophe completely destroyed the existing life, each new creation consisted of life form different from that of previous ones.

4. Theory of Panspermia/Cosmozoic theory: According to this theory, life has come to earth from other planets of the universe in the form of highly resistant spores of some organisms or microorganisms. Highly resistant spores : lead to life on earth, named as “cosmozoa or panspermia”. The cozmozoa were preserved inside meteorites. These meteorites struck into barren earth to release cosmozoa and help in development of various creature. This idea was proposed by Richter in 1865 and supported by Arrhenius (1908) and other contemporary scientists. This theory lacks evidence, hence it was discarded.

Diseases caused by Viroid: Viroids are plant pathogens. They infect higher plants and cause diseases like potato spindle tuber disease, and chrysanthemum stunt disease. These infectious RNA particles are responsible for crop failures and subsequently, the loss of millions of money in agriculture annually. Potato, cucumber, tomato, chrysanthemums, avocado, and coconut palms are plants that are commonly subjected to viroid infections. Viroids causes over 20 different plant diseases. The only human disease known to be caused by a viroid is hepatitis D. The list of diseases caused by Viroids are given below:   Transmission: Viroid infections in plants are transmitted by ➢ cross-contamination ➢ mechanical damage to plants as a result of horticultural or agricultural practices. ➢ Some seed or pollen transmitted ➢ aphids ➢ leaf contact (transferred from plant to plant) Viroid infections (hepatitis D) in humans are transmitted by ➢ blood or serum transfusions. Viroid disease control: Viro...

Theory of spontaneous generation/Theory of abiogenesis: According to this theory, living organisms could arise/originate suddenly and spontaneously from any kind of non-living matter. It is also called abiogenesis/autobiogenesis or biopoesis. Egyptians believed that mud of the Nile river could spontaneously give rise to many forms of life. Some statements on sopontaneous generation are as follows: i) Thales (624-548 BC) suggested that oceanic water was the mother from which all living forms originated. ii) According to Empedocles , life originated by itself from non living matter and imperfect forms were replaced by perfect forms. iii) Aristotle (384-322 BC): The Greek philosopher Aristotle (384-322 BC) was one of the firm believers in spontaneous generation of life. Aristotle proposed that living forms are animated forms of non-living matter. He thaught that animals might originate spontaneously from the soil, plants, or other unlike animals. He further stated that the vital...

F) Formation of colloids, co-acervates (protobionts or pre cells) or origin of primitive cell: The complex organic compounds of primordial soup in ocean aggregated together forming colloidal mass which was surrounded or bounded by water layer was called coacervates. They can grow by absorbing nutrients. Oparin called these aggregates as coacervates while Sidney fox called them Protenoids or Microspheres. The nucleic acid controlled the activities of coacervate and the fats formed a layer around it and showed a great affinity to water. This structure is called Eobiont. Some of the proteins within coacervates acted as enzymes and began metabolic activities. G) Origin of the first cell (Prokaryote): Coacervates may produce the first cell-like structure. The first cell-like structure with the power of division is called Eobiont or Pre-cell. Oparin considered that the coacervates with nucleoprotein gave rise to primitive cells or Eobionts. Oparin also called it as protobiont. The eobion...
