'Nickel famine' caused ancient oxygen rise A crucial increase in atmospheric oxygen that occurred around 2.4 billion years ago could have been triggered by a shortage of nickel in the oceans, according to Canadian researchers.   |

Airing Out an Early Atmosphere Scientists have generally thought that oxygen was scarce in Earth's atmosphere until about 2.4 billion years ago. Now a study based on new evidence suggests that oxygen may actually have been around longer than previously thought. |

Microbes Reshuffle Earth's Early History Previously, scientists used microfossil evidence to date the earliest eukaryotes to about 1.8 billion years old, and the earliest cyanobacteria to about 2.1 billion years old. Now, geologists present new evidence suggesting both types of organisms existed as early as 2.45 billion years ago. |

Volcanoes May Have Swallowed Early Earth's Oxygen New research suggests that early Earth did have oxygen during parts of the Archean (between 3.8 billion and 2.5 billion years ago), but volcanoes swallowed it up, thus preventing life from thriving. |
