Archean Eon, also spelled Archaean Eon, is the earlier of the two formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth. The Archean Eon has four major divisions. From earliest to most recent, they are the Eoarchean (4.0–3.6 Ga), the Paleoarchean (3.6–3.2 Ga), Mesoarchean (3.2–2.8 Ga), and the Neoarchean (2.8–2.5 Ga). Timelines can use any suitable scale representing time, suiting the subject and data; many use a linear scale, in which a unit of distance is equal to a set amount of time.
