Glottochronology and the comparative method of historical linguistics provide a linguistic approach for dating the common bean ( Phaseolus vulgaris L.) that both complements and supplements archaeological dating techniques such as accelerator mass spectrometry (AMS). For example, the comparative approach reveals that prehistoric languages of eastern North America having glottochronological dates earlier than 700 B.P., such as Proto‐Iroquoian (2700 B.P.), lacked words for bean. Protolanguages of the region with glottochronological dates younger than 700 B.P. had bean terms. These linguistic results accord with the AMS finding that beans do not become archaeologically visible in the region until around C.E. 1300. The earliest AMS date for beans of Mesoamerica is around 2300 B.P. This date is considerably younger than glottochronological dates for prehistoric languages of the area, such as Proto‐Mayan (3400 B.P.), for which bean terms are posited. Linguistic findings for protolanguages of Mesoamerica suggest that the regional bean chronology is considerably older than that indicated through archaeological dating.
