Explanation Biosynthesis is the term applied to the early evolution of living organisms from the simple organic building blocks found on and in the primitive Earth. The initial steps in biosynthesis are still hypothetical. It was assumed by the planetary scientists that the Sun appeared to be dull during its youth stage. It emitted very little heat such that the ocean may have been in frozen phase to a depth of about 300 meters. The ice might have developed into a blanket that upheld most of the ocean fluid and it became comparatively warm. Episodic fiery impacts by comets, asteroids, and meteor swarms could have melted the ice, but between batterings it would have restructured. Chemists Jeffrey Bada and Antonio Lazcano, in 2002, proposed that organic material may have developed and then been locked underneath the ice, which is protected from the atmosphere and consisted of chemical compounds that are potential enough to shatter the composite molecules. The initial self-sustaining living molecules might have appeared deep beneath the layers of the surface ice on pyrite crystals or clays at cool mineral-enriched seeps present on the ocean floor...
