Home > Chemical evolution

Chemical evolution is a hypothesis which tries to explain how life might possibly develop from non-life (see abiogenesis). Various experiments have been made to show certain aspects of this process, the first ones were done by Stanley L. Miller in the 1950s. For that they are now called Miller experiments. However only very basic organic building blocks were obtained. The challenge is getting complex molecules organized consistently.

Chemical equilibriumChemical equilibrium is the state in which a chemical reaction proceeds at the same rate as its reverse reaction; the rates of the forward and reverse reactions are equal, and the concentration of the reactants and products stop changing. When this conditChemical elementA chemical element often called simply element is a substance that cannot be divided or changed into different substances by ordinary chemical methods.

Chemical bondIn chemistry, a chemical bond is the force which holds together atoms in molecules or crystals. In many simple compounds, valence bond theory and the concept of oxidation number can be used to predict molecular structure and composition.

The term economics is important here.
