    “…Finally, we describe asymmetric introgression events occurring among common bean subpopulations in Mesoamerica and across hemispheres. CONCLUSIONS: We uncover an unpredicted speciation event in the tropical Andes that gave rise to a sibling species, formerly considered the “wild ancestor” of P. vulgaris, which diverged before the split of the Mesoamerican and Andean P. vulgaris gene pools. …”
