The energy expansions of evolution : Nature Ecology & Evolution

https://www.nature.com/articles/s41559-017-0138

The history of the life–Earth system can be divided into five 'energetic' epochs, each featuring the evolution of life forms that can exploit a new source of energy. These sources are: geochemical energy, sunlight, oxygen, flesh and fire. The first two were present at the start, but oxygen, flesh and fire are all consequences of evolutionary events
