Contributions of Genomics to Lipid Biomarker Research: From Paleoclimatology to Evolution Open
Lipid biomarkers can be preserved over long geological timescales. They are widely used as taxonomic markers of past and present microbial communities and as parts of organic paleoclimate proxies. However, questions remain regarding the pr…
