If you found yourself in a cocktail bar with a Neanderthal man, what would he say? A good conversation is one of the great joys of being human, but it is not clear just how far back in the hominid lineage the ability to use language stretches. The question of when grunts and yelps turned into words and phrases is a tricky one. One way of trying to answer it is to look in the fossil record for evidence about what modern humanity's closest relatives could do.
Svante P??bo, of the Max Planck Institute for Evolutionary Anthropology in Leipzig, and his colleagues have done just that. Dr. P??bo is an expert in extracting and interpreting the DNA of fossils. As he reports in the latest issue of Current Biology, he and his team have worked their magic on a gene called FOXP2 found in Neanderthal remains from northern Spain. The reason for picking this particular gene is that it is the only one known so far to have a direct connection with speech. In 1990, a family with an inherited speech disorder known as verbal dyspraxia drew the attention of genetics researchers. Those researchers identified a mutation in FOXP2 as the cause of the dyspraxia.
Since then FOXP2 has been the subject of intensive study. It has been linked to the production of birdsong and the ultrasonic musings of mice. It is a conservative type, not changing much from species to species. But it has undergone two changes since humans split from chimpanzees 6m years ago, and some researchers believe these changes played a crucial role in the development of speech and language.
If these changes are common to modern humans and Neanderthals, they must predate the separation of the line leading to Homo sapiens from the one leading to Homo neanderthalensis. Dr. P??bo's research suggests precisely that: The FOXP2 genes from modern humans and Neanderthals are essentially the same. To the extent that the gene enables language, it enables it in both species.
There has been much speculation about Neanderthals' ability to speak. They were endowed with a hyoid bone, which anchors the tongue and allows a wide variety of movements of the larynx. Neanderthal skulls also show evidence of a large hypoglossal canal. This is the route taken by the nerves that supply the tongue. As such, it is a requisite for the exquisitely complex movements of speech. Moreover, the inner-ear structure of Homo heidelbergensis, an ancestor of Neanderthals, shows that this species was highly sensitive to the frequencies of sound that are associated with speech.
That Neanderthals also shared with moderns the single known genetic component of speech is another clue that they possessed the necessary apparatus for having a good natter. But suggestive as that is, the question remains open. FOXP2 is almost certainly not “the language gene”. Without doubt, it is involved in the control and regulation of the motions of speech, but whether it plays a role in the cognitive processes that must precede talking remains unclear—jokes about engaging brain before putting mouth in gear notwithstanding. The idea that the forebears of modern humans could talk would scupper the notion that language was the force that created modern human culture—otherwise, why would they not have built civilisations? But it would make that chat with a Neanderthal much more interesting.

1. Which one of the following statements is NOT true of Neanderthal men?
[A] They are derived from a branch of early Neanderthals called Homo heidelbergensis.

1. 關(guān)于尼安德特人,下列哪個陳述是錯誤的?
[A] 他們源自早期名叫海德爾堡人的尼安德特人的一支。
[B] 他們是智人現(xiàn)存的后代。
[C] 他們是智人最近的親屬。
[D] 他們在學術(shù)界的官方名稱是尼安德特人。
答案:C 難度系數(shù):☆☆☆
分析:細節(jié)題。選項A,根據(jù)文章第五段:the inner-ear structure of Homo heidelbergensis, an ancestor of Neanderthals說明海德爾堡人是尼安德特人的祖先,而該選項混淆了二者的關(guān)系,因而是不正確的。選項B,尼安德特人是一種原始人類,因此B是錯誤的。選項C,從文章的分析來看,尼安德特人和智人有許多共同點,可能是其最近的親屬。因此,答案為C。選項D看似正確,具有較強的干擾性,但其實該說法文章中沒有提到。
2. Svante P??bo and his team carried out a study on FOXP2 in order to _____.
[A] trace the appearance and evolution of the speech ability
[B] find out how far back in the hominid lineage the ability to use language stretches
[C] find evidence proving the gene which controls the motion of speech
[D] identify the crucial changes that had taken place on this gene and the consequent influence
2. Svante P??bo和其團隊開展了一項對FOXP2的研究,目的是為了 _____。
[A] 追尋語言能力的出現(xiàn)和發(fā)展
[B] 找出原始人類使用語言的能力要追溯到什么年代
[C] 找到能證明這種基因控制語言活動的證據(jù)
[D] 找出在該基因上發(fā)生的重要變化以及相應(yīng)的影響
答案:A 難度系數(shù):☆☆☆
分析:推理題。結(jié)合第一段和第二段,首先第一段指出:The question of when grunts and yelps turned into words and phrases is a tricky one. 即他們?yōu)榱苏页龉緡伮暿裁磿r候轉(zhuǎn)變成了單詞和短語才進行這項研究的,之后,文章主要談?wù)摰脑掝}就是語言能力是在什么時候出現(xiàn)和發(fā)展的。因此,正確答案為A。
3. The gene of FOXP2 is regarded as a gene with a direct connection with speech because _____.
[A] it was found in Neanderthal remains from northern Spain
[B] it was found that sudden change of FOXP2 may lead to speech disorder
[C] it was linked to the production of birdsong and the ultrasonic musings of mice
[D] it does not change much from species to species
3. FOXP2基因被看作是和語言有直接聯(lián)系的基因,因為 _____。
[A] 在西班牙北部的尼安德特人遺骸中發(fā)現(xiàn)了這種基因
[B] 人們發(fā)現(xiàn)FOXP2突變可能會導(dǎo)致語言障礙
[C] 該基因與鳥類的歌唱和老鼠的超聲波的產(chǎn)生相關(guān)
[D] 各物種間該基因的變化不大
答案:B 難度系數(shù):☆☆☆
分析:推理題。根據(jù)第二段:In 1990, a family with an inherited speech disorder known as verbal dyspraxia drew the attention of genetics researchers. Those researchers identified a mutation in FOXP2 as the cause of the dyspraxia. 即有著遺傳性語言障礙——語言運動障礙的一個家族引起了基因研究者的注意,而研究者認為,F(xiàn)OXP2突變是這種語言障礙的原因,因此被緊密聯(lián)系了起來。因此,答案為B。
4. The word “scupper” (Line 6, Paragraph 6) most probably means _____.
[A] deny
[B] defeat
[C] demolish
[D] destroy
4. scupper這個詞(第六段第六行) 最有可能的意思是 _____。
[A] 否定
[B] 打敗
[C] 摧毀
[D] 毀壞
答案:A 難度系數(shù):☆
分析:猜詞題。根據(jù)上下文,現(xiàn)代人的祖先要是可以說話,就會推翻語言是現(xiàn)代人類文化創(chuàng)造的力量這樣的論點,因此,選項A最為符合這個意思。
5. From the findings of Dr. P??bo's research, it can be inferred that _____.
[A] FOXP2 is the gene that enables the speech ability in both humans and Neanderthals
[B] the fork separating the line leading to Homo sapiens from that to Homo neanderthalensis is wrong
[C] more important genes should be identified which control speech ability and cognitive process
[D] the establishment of human civilization as a result of language ability might be false
5. 從P??bo博士研究的發(fā)現(xiàn)可以推導(dǎo)出 _____。
[A] FOXP2就是使人類和尼安德特人擁有語言能力的基因
[B] 分割智人和尼安德特人的分割點是錯誤的
[C] 應(yīng)該找出那些控制語言能力和認知過程的更加重要的基因
[D] 語言能力創(chuàng)造現(xiàn)代人類文明這一論點是錯誤的
答案:B 難度系數(shù):☆☆☆☆
分析:細節(jié)題。根據(jù)第四段:如果現(xiàn)代人類和穴居人有共同的變化,那么他們就必須將智人和尼安德特人的分界年代推前了。P??bo博士的研究也說明了這一點:現(xiàn)代人和尼安德特人的FOXP2基因基本相同。由此可以得出,分割智人和尼安德特人的分割點是錯誤的。因此,答案為B。其余的幾點并不是P??bo博士的研究可以推導(dǎo)出的。選項A錯誤的原因在于,文章最后一段明確提出“FOXP2幾乎肯定不是‘語言基因’”。選項C在文中沒有相應(yīng)的內(nèi)容。而選項D也是錯誤的,因為根據(jù)最后一段:The idea that the forebears of modern humans could talk would scupper the notion that language was the force that created modern human culture—otherwise, why would they not have built civilisations?可見這種說法不是研究的結(jié)論,而只是一個猜測而已。
如果你在雞尾酒吧里發(fā)現(xiàn)身旁有一個尼安德特人,他會說些什么呢?比較好的話題就是,作為人類是多么快樂的一件事,但是這種原始人類使用語言的能力要追溯到哪里就不清楚了。什么時候咕噥聲轉(zhuǎn)變成了單詞和短語,這個問題很難回答。從化石記錄中找出證據(jù),看看與現(xiàn)代人類血緣關(guān)系最近的血親能夠做些什么,這是嘗試回答該問題的一條途徑。
萊比錫Max Planck進化人類學研究院的Svante P??bo及其同事就進行了這種嘗試。P??bo博士是提取并解讀化石中DNA的專家,在最新一期的《當代生物學》中,他報告了自己帶領(lǐng)的小組在西班牙北部的尼安德特人遺骸中發(fā)現(xiàn)的一種叫FOXP2的基因,并對此進行了研究。選擇這種特殊的基因是因為這是到目前為止唯一能與語言有直接關(guān)系的基因。1990年,一個有著遺傳性語言障礙——語言運動障礙的家族引起了基因研究者的注意。這些研究者認為,F(xiàn)OXP2突變是這種語言障礙的成因。
自那之后,F(xiàn)OXP2成為熱門的研究對象,甚至還有人將它與鳥類的歌唱和老鼠的超聲波聯(lián)系了起來。這種基因是守恒類型,物種之間的變化不大。但是自從人類于600萬年前由黑猩猩中分離出來后,該基因已經(jīng)發(fā)生了兩次變化,一些研究者認為,這些轉(zhuǎn)變在說話和語言的發(fā)展中發(fā)揮了重要作用。
如果現(xiàn)代人和尼安德特人有共同的變化,那么他們就必須將智人和尼安德特人的分界年代推前了。P??bo博士的研究也說明了這一點:現(xiàn)代人和尼安德特人的FOXP2基因基本相同。如果該基因賦予了人類語言能力,那么這兩個物種應(yīng)該都有這種能力。
關(guān)于尼安德特的說話能力有許多猜測。他們的舌骨支撐著舌頭,使得喉部可以自如地運動。尼安德特人的頭骨也顯示出他們擁有大的舌下神經(jīng)通道,這是舌神經(jīng)經(jīng)過的路線。同樣,這也是實現(xiàn)說話這個復(fù)雜活動的一個必備條件。而且,尼安德特人的祖先海德爾堡人的內(nèi)耳構(gòu)造表明,該物種對語音頻率有著非常高的敏感性。
尼安德特人和現(xiàn)代人還擁有到目前為止已知的共同的發(fā)音基因,這是證明他們擁有聊天所必需的器官的另外一個線索。但是雖然情況可能如此,這還是個開放的問題。FOXP2幾乎肯定不是“語言基因”。毫無疑問,該基因與控制和調(diào)節(jié)語言活動有關(guān),但它是否在語言產(chǎn)生之前的認知過程中發(fā)揮了作用還是個未解之謎,盡管有笑話說,動嘴前要先動腦。如果現(xiàn)代人的祖先能夠說話,這將推翻語言是創(chuàng)造現(xiàn)代人類文化的力量這樣的論點,否則,祖先們怎么沒有創(chuàng)造出文明來呢?但如果人類的祖先可以說話,那么和尼安德特人聊天就變得有意思多了。
