New research suggests oxygen may have been made on Earth hundreds of millions of years before its debut in the atmosphere. MIT researchers found evidence that tiny aerobic organisms may have evolved to survive on extremely low levels of the gas in these undersea oases. Former MIT graduate student Jacob Waldbauer found while working with colleagues that yeast is able to produce key oxygen-dependent compounds, even with only minuscule puffs of the gas. The research suggests that early...

NASA -- NASA exobiology researchers confirmed Earth's oceans were once rich in sulfides that would prevent advanced life forms, such as fish and mammals, from thriving. The research was funded in part by NASA's exobiology program. A team of scientists from the Massachusetts Institute of Technology and Harvard University, working with colleagues from Australia and the United Kingdom, analyzed the fossilized remains of photosynthetic pigments preserved in 1.6 billion-year-old rocks from the...
