Last glacial period
The last glacial period, popularly known as the Ice Age was the most recent glacial period within the Quaternary glaciation occurring during the last one hundred thousand years of the Pleistocene, from approximately 110,000 to 12,000 years ago. Scientists consider this ""ice age"" to be merely the latest glaciation event in a much larger ice age, one that dates back over two million years and has seen multiple glaciations. During this period, there were several changes between glacier advance and retreat. The maximum extent of glaciation within this last glacial period was approximately 22,000 years ago. While the general pattern of global cooling and glacier advance was similar, local differences in the development of glacier advance and retreat makes it difficult to compare the details from continent to continent (see picture of ice core data below for differences).From the point of view of human archaeology, it falls in the Paleolithic and Mesolithic periods. When the glaciation event started, Homo sapiens was confined to Africa and used tools comparable to those used by Neanderthals in Europe and the Levant and by Homo erectus in Asia. Near the end of the event, Homo sapiens spread into Europe, Asia, and Australia. The retreat of the glaciers allowed groups of Asians to migrate to the Americas and populate them.
