The Archean and Proterozoic eons follow; they produced the abiogenesis of life on Earth and then the evolution of early life.
(Notes re the graphic: Ga means "billion years"; Ma, "million years".) The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era after a geological crust started to solidify following the earlier molten Hadean Eon.
There are microbial mat fossils such as stromatolites found in 3.48 billion-year-old sandstone discovered in Western Australia.
The early continents of Columbia, Rodinia and Pannotia may have formed around this time, in that order.
Complex life, including vertebrates, began to dominate the Earth's ocean in a process known as the Cambrian explosion.
Pangaea forms and later dissolves into Laurasia and Gondwana.
Gradually, life expanded to land and all familiar forms of plants, animals and fungi began appearing, including annelids, insects and reptiles.Plants, later animals and possibly earlier forms of fungi form around this time.The early and late phases of this eon may have undergone "Snowball Earth" periods, in which all of the planet suffered below-zero temperatures.The history of Earth is divided into four great eons, starting 4,540 mya with the formation of the planet.Each eon saw the most significant changes in Earth's composition, climate and life.Volcanic outgassing probably created the primordial atmosphere and then the ocean; but the atmosphere contained almost no oxygen and so would have been toxic to most modern life including humans.
