This article discusses the role of free energy in the evolution of life and its impact on the planetary environment. From the beginning, living organisms had access to two sources of energy: geochemical energy and sunlight. Early life forms were autotrophs, using geochemical energy to react with carbon dioxide and release acetate, methane, and water. The development of oxygenic photosynthesis significantly increased the productivity and diversity of early ecosystems. The emergence of animals and their ability to actively hunt and eat other life forms led to a radical shift in the ecosystem, triggering a new tempo of macroevolutionary change and an increased impact of life on the planet. The article highlights the fundamental interplay between the evolution of life and the development of the planetary environment, and suggests that understanding energy expansions can help anticipate the paths of other life-planet systems.
