What is unusual about many of the residents of Yangsi village in China?

The remote Chinese village known as Yangsi that has baffling scientists for decades is located in the country’s southwest Sichuan Province. It’s a very unusual place, as around 40% of its population are dwarfs, who were all born and raised there.
