Yangsi, a remote village in southwest China’s Sichuan Province, has baffling scientists for decades. Around 40 percent of its inhabitants are several heads shorter than the average human being. 36 of the village’s 80 residents are dwarfs – the tallest one is about 3 ft. 10 inches tall and the shortest, 2 ft. 1 inch. That’s too large a percentage to be categorized as random occurrence, but so far no one has been able to provide a better explanation.
