This broad geographic origin doesn’t pinpoint a specific location for the kidney bean variety itself, but it firmly places its ancestry in the American continent.
Mesoamerica and the Andes: Two Centers of Domestication
Scientific consensus points to two primary centers of domestication for the common bean: Mesoamerica (encompassing parts of Mexico and Central America) and the Andes region of South America. These regions, geographically distinct, fostered independent domestication processes, leading to the diverse array of bean varieties we see today. It’s within this context that we can begin to understand the potential origin of the kidney bean.
While pinpointing the exact birthplace of the kidney bean is difficult, genetic studies offer valuable clues. They reveal that beans cultivated in Mesoamerica tend to have different genetic markers than those from the Andes. Understanding these genetic differences helps trace the dispersal and evolution of different bean types, including the kidney bean.
Archaeological Evidence: Beans in Ancient Diets
Archaeological digs across the Americas have unearthed bean remains dating back thousands of years. These findings provide concrete evidence of the bean’s long-standing presence in the diets of ancient civilizations. While these discoveries may not always specify the exact variety of bean, the presence of Phaseolus vulgaris in ancient sites across both Mesoamerica and the Andes bolsters the claim of its American origin.
For instance, discoveries in caves in Peru have revealed bean remains dating back over 7,000 years. Similarly, evidence from archaeological sites in Mexico suggests that beans were cultivated and consumed as early as 6,000 years ago. These findings predate European contact, confirming that beans were a staple food in the Americas long before their introduction to other parts of the world.
