单选题The study by Svante Pääbo served as an example to show ________.

A．modern genetics research is likely to fuel racial conflicts
B．race is a poorly defined marker of human genetic diversity
C．race as a biological term can explain human genetic diversity
D．genetics research should consider social and cultural variables

参考答案B
解析:由题干中的The study by Svante Pääbo定位到文章第三段第一句：“Essentially，I could not agree more with the authors，”said Svante Pääbo，a biologist and director of the Max Planck Institute for Evolutionary Anthropology in Germany．和第四段．．．．modern genetics research is operating in a paradox：on the one hand，race is understood to be a useful tool to illuminate human genetic diversity，but on the other hand，race is also understood to be a poorly defined marker of that diversity．
推理判断题。第三段第一句提到斯万特·帕博认为种族类别需要逐步淘汰，接着第四段又提
到现代遗传学研究的操作自相矛盾：一方面，种族被认为是用来说明人类遗传多样性的有用工具，但另一方面，种族又被认为是该多样性界定不清的标志。斯万特·帕博的研究也属于现代遗传学的研究，由此可知，他的研究作为示例表明种族是人类遗传多样性界定不清的标记，故答案为B.。
A.“现代遗传学研究有可能激化种族冲突”，原文并未提及种族冲突，故排除；C.“作为生物学术语，种族能够解释人类遗传多样性”，第二段后两句提到，如今，科学家们的主流观点是种族是一种没有生物学意义的社会建构，在《科学》杂志上发表的一篇文章中，四位学者表示种族类别需要逐步淘汰，而斯万特·帕博完全同意这些作者的看法，由此可知，他并不认为种族是一个生物学术语，因此，C.排除；D.“遗传研究应该考虑社会和文化变量”，第六段最后一句提到研究人员也承认，有一些地区，种族作为一个概念可能在科学研究中仍有用：当作一个政治和社会变量，而不是生物学变量，但这并非是斯万特·帕博的研究所表现的，故排除。
