What morphological characteristic resulted rapidly from the Chinese domestication method involving penning and refuse feeding?
Answer
Rounder, short-legged pigs.
The domestication efforts initiated in China approximately 9,000 years ago utilized a distinct management technique involving penning the livestock and providing them with refuse as a primary food source. This specific set of pressures rapidly drove morphological changes in the Chinese domestic stock. The resulting animals displayed distinct physical traits compared to their wild ancestors, characterized primarily by a rounder body shape and shorter legs, which became the hallmark of modern Asian domestic swine.
