英文原文阅读：

This analysis investigates the ancestry of a single modern human specimen from Australia. Evaluating its ancestry is important to our understanding of modern human origins in Australasia because the prevailing models of human origins make different predictions for the ancestry of this specimen, and others like it. Some authors believe in the validity of a complete replacement theory and propose that modern humans in Australasia descended solely from earlier modern human populations found in Late Pleistocene Africa and the Levant. These ancestral modern populations are believed to have completely replaced other archaic human populations, including the Ngandong hominids of Indonesia. According to this recent African origin theory, the archaic humans from Indonesia are classified as Homo erectus, a different evolutionary species that could not have contributed to the ancestry of modern Australasians. Therefore this theory of complete replacement makes clear predictions concerning the ancestry of the specimen WLH-50. We tested these predictions using two methods: a discriminated analysis of metric data for three samples that are potential ancestors and a pair wise difference analysis of nonmetric data for individuals within these samples. The results of these procedures provide an unambiguous refutation of a model of complete replacement within this region, and indicate that the Ngandong hominids or a population like them may have contributed significantly to the ancestry of WLH-50. We therefore contend that Ngandong hominids should be classified within the evolutionary species, Homo sapiens. The Multiregional model of human evolution has the expectation that Australasian ancestry is in all three of the potentially ancestral groups and best explains modern Australasian origins.

题型技巧分析：

人名理论配对题是考察队某个人的理论，观点，想法做配对。无序性。
建议考生先将理论做关键词的提炼，以减小之后阅读的量。然后根据文章的顺序，每个段落依次检查是否有题目中的人名出现。如果有，就阅读人名所说的话，大部分情况下是引号里的内容。要特别注意，如果出现的人名与题目无关，则就忽略。
判断题是有序原则的题目，可以根据顺序原则定位。判断题的难点在于FALSE和NOT GIVEN。抓住一个原则，原文和题目表述完全相反是FALSE，NOT GIVEN是没有提及，切不可过分推断。此外对考点词敏感度很重要，这来自于做题的经验。
TFNG题中有一道说：ancient weapon were found in the Lake。还有一题说澳大利亚派批评非洲派的研究方法不好（原文中找的是非洲派说澳大利亚派只用了一种方法，这样不好，而澳大利亚派用了2种。）
还有一个说，非洲派还是澳大利亚派不止用了一种方法做研究。
