Oparin & Haldane(1920) formed this idea separately though. In this theory‚ the basic aspects of life all came from simple molecules that formed in the atmosphere with the addition of oxygen. They believed that Earth had a chemically reducing atmosphere. This produced monomers. These monomers formed a "soup‚" that developed organic

This claim supported that of Hatch (1978) who showed a direct link between the way learners acquired a second language (l2) and the interactions
