The first humans to settle in the Americas crossed the Bering land bridge from Asia, most archaeologists agree, and Norse sailors and Christopher Columbus were among the first Europeans to set foot in the New World. Or so goes conventional wisdom.

But amateur historian and author Gavin Menzies has made a lucrative career upending conventional wisdom, starting with his controversial book "1421: The Year China Discovered the World" (William Morrow, 2002), in which he claims that a Chinese fleet helmed by Admiral Zheng He sailed to the Americas in 1421 and left behind ample archaeological and genetic evidence of their journey.
