Building the Biomarker Tree of Life (2005, background): “For example, the relative abundance of stereoisomers such as 22S vs. 22R hopanes (see 6), 20S vs. 20R steranes (see 7), or triaromatic steroids 8 with intact and cleaved side chain, often helps to estimate relative burial temperatures (e.g., Brocks et al. 2003a).”
Biosynthetic pathways, gene replacement and the antiquity of life (2004, background): “Though important new studies have recently begun to unravel the diversity of sterol biosynthesis among prokaryotes and primitive eukaryotes (Brocks et al., 2003; Pearson et al., 2003), the salient implications of biomarker synthesis on the Archean Earth demand a thorough understanding before making…”
Biogeochemical modelling of the rise in atmospheric oxygen (2006, background): “Biomarkers and carbon isotopes suggest that methanogens were present in the Archean (Hayes, 1994; Hinrichs, 2002; Brocks et al., 2003).”
A review on microbial synthesis of hydrocarbons (2006, background): “It was suggested that branched alkanes with the chain lengths from 17 to 20 carbon atoms could be used as biomarkers of cyanobacterial contributions to the sedimentary organic matter [2,23].”
The oxygenation of the atmosphere and oceans (2006, unknown): “45 Ga (Brocks et al. 2003; Summons et al. 2006).”
Evolutionary Trajectories and Biogeochemical Impacts of Marine Eukaryotic Phytoplankton (2004, background): “Perhaps more convincingly, fossil lipid biomarkers indicate that oxygenic photoautotrophs were present in the oceans by ca. 2,800 Ma (Brocks et al. 2003) and by ca. 2,300 Ma they had oxidized Earth’s atmosphere (Bekker et al. 2004).”
Targeted genomic detection of biosynthetic pathways: anaerobic production of hopanoid biomarkers by a common sedimentary microbe (2005, background): “Hopanoid biomarker data, both in more recent deposits (e.g. Hinrichs, 2001; Hinrichs et al., 2003) and in the geological record (e.g. Brocks et al., 2003a, 2003b), can no longer solely be interpreted to reflect the input of aerobic organisms or aerobic processes.”
Sterols and other triterpenoids: source specificity and evolution of biosynthetic pathways (2005, background): “More recent work demonstrating the occurrence of dinosteranes in Archean rocks suggests that this pathway may have existed for at least 2700 Ma and may have a source independent of dinoflagellates (Brocks et al., 2003).”
