Amos suggests that obstacles--such as the sea, glaciers, or mountains--on the route from Africa to the Middle East, across the Himalayas and over the Bering Strait, held many migrants back, so that a much smaller group moved on, producing offspring to inhabit new parts of the globe. As a result, "a low genetic diversity resulting from recent bottlenecks is also accompanied by the accumulation of moderately deleterious variation, which will reduce overall fitness," Godoy said.
