Protists are the dominant eukaryotes in the biosphere where they play key functional roles.
While protists have been studied for over a century, it is the high-throughput sequencing of …

The long history of life on Earth has unfolded as a cause-and-effect relationship with the

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

The transition from dominant bacterial to eukaryotic marine primary productivity was one of
the most profound ecological revolutions in the Earth's history, reorganizing the distribution …

The~ 1.6 Ga Tirohan Dolomite of the Lower Vindhyan in central India contains phosphatized
stromatolitic microbialites. We report from there uniquely well-preserved fossils interpreted …

Although the geological record indicates that eukaryotes evolved by 1.9–1.4 Ga, their early
evolution is poorly resolved taxonomically and chronologically. The fossil red alga …

Few topics in geobiology have been as extensively debated as the role of Earth's
oxygenation in controlling when and why animals emerged and diversified. All currently …

Abstract The Paleoproterozoic (2.5–1.6 Ga) Era is a decisive time in Earth and life history.
The paleobiological record (microfossils, stromatolites, biomarkers and isotopes) illustrates …

This book presents a comprehensive overview of the science of the history of life.
Paleobiologists bring many analytical tools to bear in interpreting the fossil record and the …

The Neoproterozoic Era records the transition from a largely bacterial to a predominantly
eukaryotic phototrophic world, creating the foundation for the complex benthic ecosystems …
