Clues to prehistoric human exploration found in sweet potato genometags: discoveries, Science, genetics, food, Age of Exploration
Europeans raced across oceans and continents during the Age of Exploration in search of territory and riches. But when they reached the South Pacific, they found they had been beaten there by a more humble traveler: the sweet potato. Now, a new study suggests that the plant's genetics may be the key to unraveling another great age of exploration, one that predated European expansion by several hundred years and remains an anthropological enigma.
Humans domesticated the sweet potato in the Peruvian highlands about 8000 years ago, and previous generations of scholars believed that Spanish and Portuguese explorers introduced the crop to Southeast Asia and the Pacific beginning in the 16th century. But in recent years, archaeologists and linguists have accumulated evidence supporting another hypothesis: Premodern Polynesian sailors navigated their sophisticated ships all the way to the west coast of South America and brought the sweet potato back home with them. The oldest carbonized sample of the crop found by archaeologists in the Pacific dates to about 1000 C.E.—nearly 500 years before Columbus's first voyage. What's more, the word for "sweet potato" in many Polynesian languages closely resembles the Quechua word for the plant....
