英国《每日邮报》7月20日报道,土耳其一个家庭中五兄妹都要靠四肢行走,只能短时间直立站立,膝盖和头都呈弯曲状。这五兄妹的年龄分别从18岁到34岁,他们的行走方式被称为“熊爬”。最初,科学家们认为这些人的四肢行走方式与灵长类相似,预示他们可能在“逆向进化”。来自美国纽约大学、东北俄亥俄州医学院以及亚利桑那大学的研究人员认为,这五兄妹的如此行走是一种遗传疾病的副产物, The British “Daily Mail” reported on July 20 that in a family in Turkey, all five siblings must walk on all fours, standing upright for only short periods of time with curved knees and heads. The five siblings age from 18 years old to 34 years old, their way of walking is called “bear climb ”. Initially, scientists thought the limbs of these people walked in the same way as primates, suggesting that they may be “reverse evolving.” Researchers from the University of New York in the United States, the Ohio State College in Northeast Ohio, and the University of Arizona believe that walking these five siblings is a by-product of a genetic disorder,
