Mystery: Who Brought Beans to the Lenape and Mahicans in the 1300s?

[Wicked Blue]

1. The legumes known in the Old World were broad beans, chickpeas,

lentils and peas, along with some less important vetch varieties. Pigeon peas came from the Indian subcontinent, soybeans, mung beans and adzuki were domesticated in Asia, and cowpeas in sub-Saharan Africa.

The beans we commonly eat today - kidney, navy, lima, pinto, runner - are part of the genus Phaeseolus, which originated in the Americas. They did not originate in Europe, Asia, Africa or the Middle East. It's not impossible that French or Malian explorers obtained Phaseolus beans from South America and introduced them to natives on the Atlantic coast. However Phaseolus beans could not have been imported from the Old World to the Americas.

Wikipedia:
The oldest-known domesticated beans in the Americas were found in Guitarrero Cave, Peru, dated to around the second millennium BCE.[8] Genetic analyses of the common bean Phaseolus show that it originated in Mesoamerica, and subsequently spread southward.( https://en.wikipedia.org/wiki/Bean )

Five kinds of Phaseolus beans were domesticated by pre-Columbian peoples, selecting pods that did not open and scatter their seeds when ripe: common beans (P. vulgaris) grown from Chile to the northern part of the United States; lima and sieva beans (P. lunatus); and the less widely distributed teparies (P. acutifolius), scarlet runner beans (P. coccineus), and polyanthus beans.

Broad beans have a long tradition of cultivation in Old World agriculture, being among the most ancient plants in cultivation and also among the easiest to grow. While their wild ancestor has not been identified and their origin is unknown, charred legumes of a possible wild-type progenitor have been identified at the Natufian site of the el-Wad Terrace.Carbonised domestic faba bean remains were discovered at three adjacent Neolithic sites in Israel's Lower Galilee (Yiftah'el, Ahi'hud and Nahal Zippori). Based on the radiocarbon dating of these remains, scientists now believe that the domestication of the crop may have begun as early as 8,250 BCE.
