Why Calcium? How Calcium Became the Best …

Calcium, the third most abundant metal in nature, was amply available to cells from the beginning, and was adopted as a regulator at an early evolutionary stage. The basic principles of calcium regulation were already present in prokaryotes and protists ( 3 , 4 ), but calcium regulation gradually grew to cover nearly all aspects of cell function after the transition to multicellularity.
