Ⅰ.阅读理解 (2022·青海模拟)New findings clearly show the Anglo Saxons were a melting pot of people from both migrant and local cultural groups and not one group from Western Europe. Professor Keith Dobney at the University of Sydney said the team's results state that “the Anglo­Saxon kingdoms of early Medieval Britain were clearly similar to modern Britain—full of people of different ancestries sharing a common language and culture.” Published in PLOS ONE, the cooperative study by Professor Dobney at University of Sydney and Dr Kimberly Plomp and Professor Mark Collard at Simon Fraser University in Vancouver. Looked at the three­dimensional shape of the base of the skull (头盖骨)． Previous studies have shown that the base of the human skull holds a shape signature that can be used to track relationships among human populations in a similar way to ancient DNA，“Dr Plomp said.”Based on this, we collected 3D data from suitably dated skeletal collections from Britain and Denmark, and then analysed the data to judge the ancestry of the Anglo­Saxon individuals in the sample. The researchers found that between two­thirds and three­quarters of early Anglo Saxon individuals were of continental European ancestry, while between a quarter and one­third were of local ancestry. When they looked at skeletons dated to the Middle Anglo­ Saxon period (several hundred after the original migrants arrived), they found that 50 to 70 percent of the individuals were of local ancestry, while 30 to 50 percent were of continental European ancestry, which probably indicates a change in the rate of migration and local adoption of culture over time. “These findings tell us that being Anglo­Saxon was more likely a matter of language and culture, not genetics，” Professor Collard said. The ongoing and unresolved argument is whether a lot of European invaders largely replaced the existing Romano­ British inhabitants, or did smaller numbers of migrants settle and interact with the locals, who then rapidly adopt
