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 timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
For events dating from the formation of the planet to the rise of modern humans see: Timeline of natural history, Timeline of the evolutionary history of life and Timeline of human evolution. For events dating from the first appearance of Homo sapiens to before the invention of writing see: Timeline of prehistory

The whale fossil was uncovered in the Wadi El-Rayan area, which sits about 24.9 miles (40 kilometers) northeast of the Wadi Al-Hitan World Heritage Site in Egypt’s Western Desert. The area is ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...

The evolutionary biologist Stephen Jay Gould revived earlier ideas of heterochrony, alterations in the relative rates of developmental processes over the course of evolution, to account for the generation of novel forms, and, with the evolutionary biologist Richard Lewontin, wrote an influential paper in 1979 suggesting that a change in one ...
