20 Aug 9600 Jahr v. Chr. - end of paleolithic age

Beschreibung:

hough early humans started off living in Africa, by the end of the Paleolithic Age, they had spread to the other continents. The four periods of climate change ice ages that occurred were part of humans' motivation to move. Temperatures plunged, glaciers expanded and sea levels dropped. In response, some early humans adjusted to the change, while others journeyed to new areas. Land bridges connected continents, so about 150,000 years ago humans began to move into the Middle East. It took another 90,000 years until they headed to Australia, and even longer to reach central and east Asia.
