New evidence that modern humans moved out of Africa and occupied parts of Eastern Europe as early as 45,000 years ago has been uncovered by a team of American and Russian scientists. Vance T. Holliday, a University of Arizona, Tucson, professor of anthropology and geosciences, helped excavate three and worked on six of the more than two dozen ancient sites found about 240 miles south of Moscow, Russia.

The excavations are located in the villages of Kostenki and Borshchevo, on the low terraces just above the Don River, overlooking a broad valley. Holliday says the uplands at Kostenki closely resemble rural Iowa. The area has a number of natural springs and seeps that would have been an important source of fresh water for humans and the animals they hunted.
