Even more surprising is that the genes that specify certain . In the final step of chemical evolution, protobionts developed the ability to reproduce and pass genetic information from one generation to the next. In evolutionary biology, on the other hand, the term "chemical evolution" most often is used to describe the hypothesis that organic building blocks of life were created when inorganic molecules came together. The first atmosphere was made up of hot hydrogen gas, too light to be held by Earth's gravity. Chemical reactions often involve color changes, temperature changes, gas production, or precipitant formation. We believe in learn by doing. Scoville, Heather. Chem. The majority of Earth is covered by the oceans. In the second stage of chemical evolution, the simple organic molecules (such as amino acids) that formed and accumulated joined together into larger structures (such as proteins). Sydney Fox of the University of Miami suggested that waves or rain in the primitive environment splashed organic monomers on fresh lava or hot rocks, which would have allowed polymers to form abiotically. "Did Life Have a Simple Start?" Scientists today state that such spontaneous synthesis occurred only in the primitive environment. Heat produced by compaction, radiation, and impacting meteorites melted Earth. This concept was first proposed in 1936 in a book entitled, “ The Origin of Life on Earth, ” by the Russian scientist, Aleksandr Ivanovich Oparin (1894 – 1980).
