The rapidly expanding universe of giant viruses: Mimivirus, Pandoravirus, Pithovirus and Mollivirus
C Abergel, M Legendre… - FEMS microbiology …, 2015 - academic.oup.com
More than a century ago, the term 'virus' was introduced to describe infectious agents that
are invisible by light microscopy and capable of passing through sterilizing filters. In addition …

Deconstructing the Lomagundi-Jatuli carbon isotope excursion
The early to mid-Paleoproterozoic Lomagundi-Jatuli Excursion (LJE) is ostensibly the
largest magnitude (approximately+ 5 to+ 30‰), longest duration (ca. 130–250 million years) …

[HTML][HTML] The Paleoproterozoic fossil record: implications for the evolution of the biosphere during Earth's middle-age
EJ Javaux, K Lepot - Earth-Science Reviews, 2018 - Elsevier
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 …

Oxygen suppression of macroscopic multicellularity
Atmospheric oxygen is thought to have played a vital role in the evolution of large, complex
multicellular organisms. Challenging the prevailing theory, we show that the transition from …

Frameworks for interpreting the early fossil record of eukaryotes
The origin of modern eukaryotes is one of the key transitions in life's history, and also one of
the least understood. Although the fossil record provides the most direct view of this process …

Earth's surface oxygenation and the rise of eukaryotic life: Relationships to the Lomagundi positive carbon isotope excursion revisited
The availability of molecular oxygen shapes the size and structure of Earth's biosphere.
Geological and geochemical records imply that, for most of the Precambrian (the entirety of …

Selenium isotopes record extensive marine suboxia during the Great Oxidation Event
It has been proposed that an “oxygen overshoot” occurred during the early Paleoproterozoic
