Archaeologists contend that Paleo-Indian migration out of Beringia (eastern Alaska), ranges from 40,000 to around 16,500 years ago. This time range is a hot source of debate and promises to continue as such for years to come. The few agreements achieved to date are the origin from Central Asia, with widespread habitation of the Americas during the end of the last glacial period, or more specifically what is known as the late glacial maximum, around 16,000–13,000 years before present. However, older alternative theories exist, including migration from Europe.
