achieved remarkable levels of metabolic sophistication before the end of the Archean around 2500 Ma (2, 3). The great antiquity of our biosphere might indeed illustrate how easily life can arise on a habitable planet, but it also portends the challenges that confront our efforts to become intimately familiar with our earliest ancestors. The earliest sedimentary rocks have typically undergone extensive alteration by metamorphosis, taking a serious toll on microfossils (4). Fortunately, memories of our distant forebears are recorded not only in ancient rocks, but also in biological macromolecules (5) and pathways. The two records are highly complementary: The geologic record offers the absolute timing of evolutionary innovations and their env...
