Origin of life Essay

In the unofficial given, theory of bearing is state to pass risen from the primitive mans atmosphere. The atmosphere of the earlier earth is utter to have many carbon dioxides but no oxygen. These carbon dioxides will act as reactants in order to give much more complex organic substances such as proteins, carbohydrates lipids, phospholipids, and nucleotides. The said substances are well known as the grammatical construction blocks of life. This is the evidence that entertains their form of address that life originated from the gases present in the archaeozoic earths atmosphere. withal to support their claims, an experiment during the early 1950s would confirm that it is true that guileless carbon based compounds can naturally be created under the surround of the primitive earth. In other readings, the early life is said to have also talks about the construction blocks of life. The Panspermia theory proposed that these building blocks of life would have originated outdoo r(a) of the earth. These building blocks or the seed of life energy be scattered around the galaxy or even the universe. in like manner the same as the compend in piecing it together, the panspermia theory suggests that whenever conditions are met, the building blocks of life will grow and develop. The only downfall of the theory is that, since the building blocks of life came from outside the earth, then there is a great mishap that other life may form from outside of the earth. Evidence of this theory is that, a certain bacteria were discovered in the earths upper atmosphere. Whats interesting with the discovery is that the bacteria were similar to the bacteria found in the earth. The bacteria might brought by the space crafts that go forth the earth.But still, there is a probability that the bacteria would have evolved from outside of the earth. Unfortunately, this theory is lacking in evidence. Some scientists are still on the verge of research in order to prove that their c laims were right (Backman, 2007). The summary has a basis about its claims of the origin of life. But problems arise. The origin of the earth is still not established very well. It is said in the summary that substances from the early earth will evolve but the existence of the early earth is not yet been proved. Both the theories lack evidence to support claims of the origin of life.
