hnkstrprnkstr writes “MIT scientists have created a sort of genomic fossil (abstract) that shows the collective genome of all life underwent an enormous expansion about 3 billion years ago, which they’re calling the Archean Expansion. Many of the new genes appearing in the Archean Expansion are oxygen related, and could be the first biological evidence of the Great Oxidation Event, the period in Earth’s history when oxygen became so plentiful that many anaerobic life forms may have become extinct.”
