It got its own Gordon Research Conference in 2011, [ 12 ] a number of geobiology textbooks have been published, [ 3 ] [ 13 ] and many universities around the ...
This timeline of natural history summarizes significant geological and biological events from the formation of the Earth to the arrival of modern humans. Times are listed in millions of years, or megaanni ( Ma ).
1809 – William Maclure conducts the first geological survey of the eastern United States 1813 – Georges Cuvier publishes his Essay on the Theory of the Earth, proposing catastrophism on the basis of his work in biostratigraphy
Geologic time shown in a diagram called a geological clock, showing the relative lengths of the eons of Earth's history and noting major events The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale , a system of chronological measurement based on the study of the planet's rock ...
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
The second timeline shows an expanded view of the most recent eon. In a similar way, the most recent era is expanded in the third timeline, the most recent period is expanded in the fourth timeline, and the most recent epoch is expanded in the fifth timeline.
