While Haeckel's tree is outdated, it illustrates clearly the principles that more complex and accurate modern reconstructions can obscure. 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 ...
At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
There is some evidence that modern humans left Africa at least 125,000 years ago using two different routes: through the Nile Valley, the Sinai Peninsula and the Levant (Qafzeh Cave: 120,000–100,000 years ago); and a second route through the present-day Bab-el-Mandeb Strait on the Red Sea (at that time, with a much lower sea level and ...
Layers dating from between 250,000 and 140,000 years ago in the same cave contained tools of the Levallois type which could put the date of the first migration even earlier if the tools can be associated with the modern human jawbone finds.

Human history or world history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers. They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
Modern humans ventured into northern Europe under extremely cold climate conditions and were living side by side with Neanderthals more than 45,000 years ago, according to new evidence.
A new analysis of the 25-foot-long (7.6-meter-long) bridge inside Genovesa Cave has revealed that humans lived on Mallorca, one of the largest islands in the Mediterranean, much earlier than ...
[58] [59] Further, there is no evidence that humans ate fish in significant amounts earlier than tens to hundreds of thousands of years ago. [60] Supporters argue that the avoidance of taphonomic bias is the problem, as most hominin fossils occur in lake-side environments, and the presence of fish remains is therefore not proof of fish ...
