What is the timeline of human?
However, the age of the oldest remains of the genus Homo is younger than this technological milestone, dating to some 2.8–2.75 million years ago in Ethiopia. The oldest known remains of Homo sapiens—a collection of skull fragments, a complete jawbone, and stone tools—date to about 315,000 years ago.
When did humans first appear on Earth timeline?
The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2.5 million years ago. Then some of them spread from Africa into Asia and Europe after two million years ago.

How many stages of human evolution are there?
four stages
Humans began to evolve about seven million years ago, and progressed through four stages of evolution. Research shows that the first modern humans appeared 200,000 years ago.
How old is the Earth timeline?
4.54 billion years old
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.

Who was the first man in history?
The First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
What is the timeline of human evolution?
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 4.2 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
When did humans first appear?
Here’s a breakdown of the human timeline: HOMO SAPIENS: The earliest anatomically modern human (Homo sapiens) fossil found was dated at 200,000 years old in Morocco, Africa. They had modern faces and used stone tools. HOMO HABILIS: But if you look at our genus (Homo), Homo Habilis arose 2.8 million years ago in Africa.
How long ago did hominids emerge?
Hominins which includes human species and immediate ancestors emerged about 7 million years ago in Africa. Finally, hominids which includes gorillas, orangutans, chimpanzees, bonobos and humans existed 11 to 16 million years ago.
When did modern man first appear?
Anatomically modern humans arose in Africa about 300,000 years ago, and achieved behavioral modernity about 50,000 years ago. The Paleolithic period began with the advent of hominid tool use. Hominids, such as Homo erectus had used simple wood and stone tools for millennia, but as time progressed, tools became far more refined and complex.
