Primordial Soup Theory
This paper is about 6 theories of how the world began. This includes: The primordial soup theory, the iron-sulfur theory, RNA world theory, deep sea vent theory, community clay theory, and the panspermia theory. Each theory is a different hypothesis on how life on earth began throughout the course of over 1,000 years.

Primordial Soup Hypothesis
Alexander Oparin (introduced hypothesis) and Robert Shapiro (summarized paper) presented the primordial soup theory in 1924. 3.8 billion to 3.55 billion years ago life began in a pond or ocean as a result of the combination of chemicals from the atmosphere and some form of energy to make amino acids, the building blocks of proteins, which would …show more content…
In the study, scientists speculate that clay hydrogels provided a platform for chemicals to come together and form complex biomolecules. Experiments using water samples that resemble ancient seawater have shown that clay forms a hydrogel under certain conditions. Hydrogel is a network of polymer chains that has the ability to soak-up huge quantities of water. Basically, these gels are super-sponges. Over billions of years, the trapped chemicals reacted and formed biochemicals such as proteins and DNA.
Panspermia Hypothesis
The first known mention of the concept of panspermia was in the writings of the Greek philosopher Anaxagoras (500 BC – 428 BC).The panspermia hypothesis states that the "seeds" of life exist all over the Universe and can be propagated through space from one location to another. Some believe that life on Earth may have originated through these "seeds". Several tests
