Researchers on the island of Flores recently unveiled the remains of what appeared to be a female adult human a meter tall that lived as recently as 13,000 years ago. The news electrified the paleoanthropological community. It clearly belonged to the hominid family—the group of species on the human side of the evolutionary line from prehuman primates. Hominids of this size had been documented only from fossils of species that lived three million years ago. Scientists had thought that modern humans were the only hominid species to have existed for the past 25,000 years.

Classifying the skeleton was difficult. Some of its features show it belongs in the Homo genus—a genus within the hominids that includes the modern human species, Homo sapiens. But its morphological traits are inconsistent with those of small-bodied, modern-human adults. The skeleton exhibits archaic features—for example, a prominent brow and low braincase—not characteristic of Homo sapiens.

Researchers concluded that some members of an earlier hominid species, Homo erectus, had evolved in isolation on Flores and that the skeleton belonged to a species that emerged from that evolution. In island habitats, large-mammal species tend to get smaller, presumably adapting to a limited food supply. Many scientists had believed that culture buffered humans from such environmental pressures. The discovery of a diminutive hominid species may indicate that in difficult times, humans respond like other mammals.

1.The primary purpose of the passage is to

A. illustrate potential applications of research findings

B. dispute the theoretical relevance of newly discovered evidence

C. suggest future studies on a topic of research

D. report the findings of a scientific study

E. critically compare one interpretation of research findings with another

2.Which of the following most accurately summarizes the second paragraph?

A. The skeleton is most likely a member of Homo sapiens, possessing features, however, that are somewhat untypical of modern humans.

B. Some morphological characteristics of the skeleton were unique neither to Homo sapiens nor to any other members of the Homo genus.

C. The skeleton, though it belongs to a species in the Homo genus, has features showing it is not a small-bodied Homo sapiens.

D. The prominent brow and low braincase of the skeleton misled researchers into thinking that the skeleton did not belong to a species within the Homo genus.

E. Though at first sight the skeleton appeared to belong to a species within the Homo genus, the physical evidence, when carefully examined, disconfirmed this.

3.The passage most strongly supports which of the following inferences regarding the skeleton discovered on Flores?

A. Its discovery provided data that presented a challenge to widely held beliefs among scientists concerning hominid species.

B. It belonged to a species that is most likely an ancestor of modern humans.

C. Prior to its discovery researchers had thought modern humans were the only hominid species.

D. The researchers who discovered it believed at first that the skeleton belonged to a genus other than the Homo genus.

E. Its discovery provided significant new information about the ancestor species of Homo erectus.

dcb 正答DCA错题解析3.E是提供了new information about hominids，Homo erectus是新发现的物种，不存在new information
B跟现代人属于Homo genus的另一个分支Homo erectus
C缺少时间范围的限制, the only hominid species to have existed for the past 25,000 years.
A正答，文章用了两个had done表示该新发现推翻了之前观点

1. 研究学家在F岛发现一具残骸（存活在13000年前），它明显归属于人类一族，这个体型的人类以前只在300万年前的化石中记录，过去科学家认为现代人是过去25000年中唯一的人类种族
2. 把这个残骸归类是困难的，有些特征显示它属于home genus（这类中包括现代人），但是其中某些特质和小体型的现代人不符，比如archaic features
3. 提出另一个观点：早期的人类种族中的一种home erectus但F岛上单独进化，由于食物稀缺，大型哺乳动物题型变小了，这个发现暗示人类在困难时期可能respond like mammals

1.新发现的人类骨骼挑战科学家认知:出土一具骨骼属于原始人类。这种大小的骨骼只有在300万年前的骨骼化石中发现
2.辨别骨骼的难点:一些特征表明属于Homo genus，包含现代人类，智人。BUT有所不同，假如：例子
3.3.结论：属于Homo erectus:给出结论的解释：由于环境因素所以进化得比较小。大型动物一般会变小，人们以前had 以为人类免于了这种环境因素，其实不是的。
