Like exhausted nightclubbers, early animals may have weathered their harsh lifestyle by squirming up to the oxygen bar.

Animals living more than 550 million years ago could have survived inhospitable oceans by associating with dense mounds of cyanobacteria called microbial mats, an international team of researchers argues in a new study.
