In 1971, archaeologist Wilhelm “Bill” Solheim made some comments in the magazine National Geographic about the origins of agriculture. His comments were premature, and turned out to be false.

They now serve as “evidence” to support the idea that the ancestors of the Vietnamese were the first people in Asia to cultivate wet rice and that they introduced this technology to the Han Chinese.
