Did humans evolve from trees?
The last common ancestor of humans and chimpanzees may have had shoulders that were similar to those of modern African apes, researchers say. The finding supports the notion that the human lineage shifted to a life away from trees gradually.

Will humans go extinct in 2100?
In 2008, an informal survey of experts on different global catastrophic risks at the Global Catastrophic Risk Conference at the University of Oxford suggested a 19% chance of human extinction by the year 2100.
What were humans doing 100000 years ago?
Between 70,000 and 100,000 years ago, Homo sapiens began migrating from the African continent and populating parts of Europe and Asia. They reached the Australian continent in canoes sometime between 35,000 and 65,000 years ago. Map of the world showing the spread of Homo sapiens throughout the Earth over time.
How was the world 10000 years ago?
In the Paleolithic period (roughly 2.5 million years ago to 10,000 B.C.), early humans lived in caves or simple huts or tepees and were hunters and gatherers. They used combinations of minerals, ochres, burnt bone meal and charcoal mixed into water, blood, animal fats and tree saps to etch humans, animals and signs.
How long did humans live for?
Variation over time
| Era | Life expectancy at birth in years |
|---|---|

How did humans get all over the world?
The so-called “recent dispersal” of modern humans has taken place after beginning about years ago. It is this migration wave that led to the lasting spread of modern humans throughout the world. Other research supports a migration out of Africa between about 65,000 and 50,000 years ago.
Where was the body of the first man found?
The oldest directly dated human remains have turned up in a Bulgarian cave. The tooth and six bone fragments are more than 40,000 years old. The new discoveries came from Bulgaria’s Bacho Kiro Cave. They support a scenario in which Homo sapiens from Africa reached the Middle East some 50,000 years ago.
