英文:Recently, archaeologists in Chile found chicken bones which they subsequently radiocarbon dated as approximately 600 years old. Using DNA testing, Alice Storey of the Allan Wilson Centre for Molecular Ecology & Evolution at the University of Auckland discovered that the bones from Chile carried a rare mutation otherwise only found in chickens from Mele Havea, Tonga, and Fatu-ma-Futi, American Samoa. Previously, scientists commonly believed that the chicken, not indigenous to either North or South America, arrived on the continent along with Spanish explorers in the 15th century. However, if Chileans in fact possessed chickens at least 100 years before Columbus reached America, and these fowl carried DNA identical to chickens found in Tonga and Tutuila, this evidence clearly indicates a pattern of interaction between Polynesians, long recognized as some of the world’s finest sailors and navigators in times preceding Western contact, and South Americans. To put it simply, Polynesians not only made it to America before Columbus, but they apparently introduced the chicken to the continent, as well.作者: skyyanforeve 时间: 2011-11-2 01:45
