29 Μαΐ 2024 · The geologic time scale from 650 million years ago to the present, showing major evolutionary events. The evidence is overwhelming that all life on Earth has evolved from common ancestors in an unbroken chain since its origin. Darwin’s principle of evolution is summarized by the following facts.
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 layers ( stratigraphy ).
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 ).
By examining the composition of rocks and the types of fossils in them, scientists have created a timeline of Earth’s history. It is broken up into sections based on major events, like global climate changes and mass extinctions.
