The Evolution Of Cell

 The major question in the minds of men and scientist especially for centuries is centred on the "origin of life on Earth". So many scientist have proposed diverse theories and concepts that attempts to explain this mystery. Despite so many theories that have been proposed regarding this subject, there are still arguments concerning this subjects. Infact many have already accepted religious propositions about the origin of life as the accurate concept. Cell evolution is a concept that have been agreed upon by many scientist to be the accurate explanation of the origin of life on Earth, although there are so many things yet to be clearly understood regarding this concept. It explains that; 3 billions years after the formation of earth, the only living things that existed on Earth were primitive microorganisms. It further explains that these early cells gave rise to biochemical systems and oxygen-enriched atmosphere on which modern Life depends. In other words, it tells us that life as we know it presently has its origin in the existence of certain small organisms that were present on the Earth about 3 billion years ago. As intelligent as this concepts looks, many people however have regarded the concept of cell evolution as fiction- a product of man's imaginative ability, hence the need to critically give a thorough explanation on the concept that have intelligently explained the Origin of life on Earth,"Cell Evolution".
