Three men were buried in Mexico 500 years ago. DNA and bones reveal their stories of enslavement
In the late 1980s, workers excavating a new subway line in downtown Mexico City stumbled upon a long-lost cemetery. Documents showed it had once been connected to a colonial hospital built between 1529 and 1531—only about 10 years after the Spanish conquest of Mexico—for Indigenous patients. As archaeologists excavated the buried skeletons, three stood out. Their teeth were filed into shapes similar to those of enslaved Africans from Portugal and people living in parts of West Africa. Now, chemical and genetic analyses confirm these individuals were among the first generation of Africans to arrive in the Americas, likely as early victims of the burgeoning transatlantic slave trade.
