Origin and evolution of life. the miller urey experiment simulated early earth conditions and provided evidence supporting the hypothesis that organic compounds could form naturally through non biological means. in the experiment, stanley miller and harold urey created a mixture of gases thought to exist in the early atmosphere methane.

The origin and early evolution of life chapter 18. learning objectives • differentiate between chemical evolution and organic evolution. • describe the conditions on the primitive earth predicted by laboratory experiments that favored the spontaneous development of organic molecules. • explain the probable sequence in the origin of the. Life likely arose between 3.85 3.5 billion years ago, as evidenced by stromatolites and microfossils from that period. experiments show organic molecules can form naturally through chemical reactions in the atmosphere and near hydrothermal vents on the early earth. it is proposed that self replicating rna molecules were able to evolve through.
