A key turning point was when oxygen accumulated in the atmosphere around 2.3 billion years ago. Scientists have used this oxygen surge and how microbes adapted to it to map out bacterial evolution.

The international team, including researchers from the University of Bristol, in the UK, and led by the Okinawa Institute of Science and Technology (OIST), in Japan, used a key evolutionary turning ...
