How did humans settle Eurasia 45 thousand years ago?
About 45 thousand years ago, Homo sapiens made Eurasia (Asia and Europe) their home. But before that, from 60-70 thousand years ago after leaving Africa till 45 thousand years ago, where did they live? This remains a mystery.
45 thousand years ago, humans made many types of stone tools in Eurasia, which shows that they were divided into different groups and their culture was also different. Some humans had gone to europe earlier, but they could not survive there and none of their descendants are present today. There is a gap of 20 thousand years between leaving Africa (60-70 thousand years ago) and settling in Eurasia (45 thousand years ago). It is not known where humans lived during this period.
Scientists believe that after leaving Africa 60-70 thousand years ago, a group of humans must have lived in one place, which is called 'hub population'. This group kept growing gradually and then spread in Eurasia. But it is difficult to find out where this hub population was because very few fossils of humans of that time have been found.
Cro-Magnon are considered the first anatomically modern humans in Europe. They entered Eurasia by the Zagros Mountains (near present-day iran and eastern Turkey) around 50,000 years ago, with one group rapidly settling coastal areas around the indian Ocean and another migrating north to the steppes of Central Asia.
