When did humans complete their expansion around the world?

Answer 1

The other answer is right as this the human presence is still expanding.

Generally though aborigines were in Australia 40,000 years ago. People also arrived in the Americas at this time (coinciding with the extinction of the wooly mammoth).

Africa of course was the origin of the human race and with land links to Europe and Asia these were fairly easily colonised.

Answer 2

This question is a little vague and open-ended. In theory, one could say that humans continue their expansion around the world today. There are still largely uninhabited tracks of land on several of the continents. With an expanding population every year, this reality is that these uninhabited areas might become a thing of the past in a few decades-depending on the advances of science & technology.

If you are referring to historical expansion into other continents, one may say that a few thousand years ago would not be unrealistic. However, there is still a lot of speculation as to who were the first settlers to the continent of North America, and when they came here-as an example.

Answer 3

The sequence, very roughly, for anatomically modern humans is:
Africa - originated there about 150,000 years ago
Asia - very shortly after
Australia - between 40,000 and 60,000 years ago
N. America - usually held to be only 14,000, but some evidence of up to 30,000
S. America - a few thousand after the North.

The last large landmass to be settled was New Zealand, within the last 2,000 years, mainly within a thousand years.

A few remote islands remained untouched by people until the 19th Century.

Answer 4

By about 8000-9000 years ago, humans had spread throughout North and South America.

Answer 5

They are still expanding, 8.5 billion individuals.
