Two models explain what is evolution?

Answer 1

Evolution is generally a very broad word, but in the context of science it takes on the meanings associated with Biology and a scientific explanation of the origin of life. Two prominent theories for biological evolution on Earth are informally called the "soup theory" and the "sandwich theory." The soup theory hold that precursor molecules floating around in liquid (soup) were combined by an electrostatic discharge like that of lightning, combined into more complex organic forms. The sandwich theory posits that crystalline surfaces below the ocean provided a kind of framework to allow simple organic molecules to co-ordinate with inorganic planes long enough to then bind to each other and float away in a more complex state. While both these models are broadly admitted to be imperfect and far from a proof, they illustrate possibilities of the nature or models of evolution wherein something simple and inorganic may become something more complex and more organic.
