Review of current evidence suggests both interior and coastal routes viable path for first migrations into North America

Credit: Potter et al., Sci. Adv. 2018;4: eaat5473An ambitious new cross-disciplinary study promises to at least partially resolve a long-running debate in science. Did the first Americans arrive via an inland land-bridge route, threading their way through ice sheets in modern-day Alaska? Or did they skirt the coastline from Asia to the Americas? According to the new analysis of archaeological, genetic, and other data, the answer is … both. Probably. The conclusion leaves a bit to be desired in terms of wager-settling, but according to the research team, it really is the most accurate assessment archaeologists can make at this point. The findings, if widely accepted, represent a potentially major shift in scientific thinking. For much of the 20th century, it was considered bedrock truth that the first Americans came to the continent via the ice free corridor — or IFC — a route between two massive ice sheets from Asia through the interior of Alaska and finally into the high plains of North A
