Oxygen levels on Earth skyrocketed 2.4 billion years ago, when cyanobacteria evolved photosynthesis:[…]. The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light. The critical component of the photosynthetic system is the “water-oxidizing complex”, made up of manganese atoms and a calcium atom.

2013 September-October, Katie L. Burke, “In the News”, in American Scientist:

(uncountable) A metallic chemical element (symbol Mn) with an atomic number of 25, not a free element in nature but often found in minerals in combination with iron, and useful in industrial alloy production.

During that period, the advantages of manganese steel, and of heat treatment by the sorbitic process, were advocated strongly on the Southern Area of that company.

1952 February, “Chromium and Sorbitic Steel Rails”, in Railway Magazine, page 73:

Cast steel containing a considerable percentage (10-14%) of manganese, which makes it very hard and tough and highly resistant to wear.
