Origin of life Essay

In the summary given, opening of life is said to have risen from the primitive lands atmosphere. The atmosphere of the early earth is said to have many carbon dioxides only if no oxygen. These carbon dioxides will act as reactants in order to create much to a greater extent complex organic substances such as proteins, carbohydrates lipids, phospholipids, and nucleotides. The said substances are well known as the twist blocks of life. This is the evidence that supports their claim that life fountated from the gases present in the early earths atmosphere.Also to support their claims, an experiment during the early 1950s would confirm that it is true that simple carbon based compounds can course be created under the environment of the primitive earth. In other readings, the early life is said to have also talks about the building blocks of life. The Panspermia theory proposed that these building blocks of life would have originated outside of the earth. These building blocks or the seed of life might be scattered around the galaxy or withal the universe.Also the same as the summary 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 possibility 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 left 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 claims were right (Backman, 2007). The summary has a basis a bout 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.
