Life on Earth first bloomed around 3.7 billion years ago, when chemical compounds in a "primordial soup" somehow sparked into life, scientists suspect. But what turned sterile molecules into living, changing organisms? That's the ultimate mystery.

And from that day, college science students have been taught that science has explained life’s origin. Indeed, many students are under the impression that life itself has been synthesized in a test tube. Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
‘So, it seems, the Earth's primordial soup was primed with the monomers for making the polymeric components of primitive life.’ More example sentences ‘Here was the starfish that turns beautiful coral polyps into ‘green slime’ - words that invoke the slime of the alien in horror movies or the primitive wildness of the primordial soup from which life on earth first came.’

In conclusion, primordial soup theory does not fully explain the process involved in the origin of life. To overcome the many limitations presented by this theory, other theories have been put forth to account for the spontaneous generation of life, but none have produced convincing evidence, so as to be widely accepted as a valid explanation. By studying the evolution of not just life, but life's building blocks as well, researchers hope to come closer to the answer. Two become one The molecules swimming in early Earth's primordial soup would have been continually destroyed by ultraviolet radiation from the sun, as well as heat and other processes on the planet. When the primordial soup is exposed to energy, organic compounds are produced as shown by the Miller-Urey Experiment.

A. Single system of life first The idea of the Primordial soup was suggested independently and simultaneously by Russian scientist Alexander Oparin and English geneticist John Haldane. They suggested that life started in the oceans spontaneously in the form of protein generated by a mix of gases in the atmosphere and energy from lightning strikes. Even though primordial soup in ancient Earth may not have been exactly the same as in the Miller-Urey experiment, their effort was still very significant. Their primordial soup experiment proved that organic molecules—the building blocks of life—can be made from inorganic materials.

These non-living, increasingly complex chemicals followed a Darwinian process of competition and natural selection and accumulated in the primitive ocean to form a primordial soup. 2018-03-05 · It had been theorized that life started in the oceans. Oparin and Haldane thought that with the mix of gases in the atmosphere and the energy from lightning strikes, amino acids could spontaneously form in the oceans.
