One of the major obstacles to a clearer understanding of the earliest history of life on Earth is uncertainty in the timing of major biological events. Identifying the births and deaths of major gene pathways will help place those events in context of relevant geochemical events in Earth history, and conversely help to constrain the timing of those events. I use a combination of culturing, bioinformatics and lipidomics to understand the role of anoxygenic phototrophs in Earth’s history and to constrain better the timing of the advent of oxygenic photosynthesis in ancient bacterial lineages.
