Bacteria helped early animals to breathe

Mats of plant-like bacteria dramatically increase local oxygen levels in the lakes where they are found, as a result of photosynthesis. That might have given early multicellular animals the boost they needed to evolve in an ancient world where oxygen was scarce.

A study exploring this idea, p... Read More
