..., namely lipids (phytol, α-tocopherol, and C 16 isoprenol) associated with photosynthesis. These lipids presumably become surplus constituents as desiccation halts photosynthesis, and strongly suggest that the microbial biosynthesis of WE utilizes primary lipids made available as organisms become...

... left the mound by way of the ocean floor and crust to colonize the deep biosphere. Once life had emerged and evolved to the extent of being able to reduce nitrogen for use in peptides and nucleic acids, light could have been used directly as an energy source for biosynthesis. Certain bacteria may...

... structure from biosynthesis, through diagenesis, catagenesis and metamorphism. This review aims to present a comprehensive, organized ‘snap shot’ of this field as it presently exists, and to predict some of the ways in which it could evolve over the next several years. We do not provide a detailed...

... is consistent with an earlier evolution of oxygenic photosynthesis than previously thought and suggests that some aquatic settings had become sufficiently oxygenated for sterol biosynthesis by this time. It also implies that eukaryotes survived several extreme climatic events, including the Paleoproterozoic...
