en competitors like wolves--spurred on human tool-making and language, which have both driven humanitys success, Pat Shipman says, paleoanthropologist of Penn State University. "Wherever you go in the world, whatever ecosystem (生态系统), whatever culture, people live with animals," Shipman said. For early humans, taking in and caring for animals would seem like a poor strategy for survival. "On the face of it, you are wasting your resources. So this is a very weird behavior," Shipman said. But its not so weird in the context something else humans were doing about 2.6 million years ago: switching from a mostly vegetarian diet to one rich in meat. This happened because humans invented stone hunting tools that enabled them to compete with other top predators. Quite a rapid and bizarre switch for any animal. So we invented the equipment, learned how to track and kill, and eventually took in animals who also knew how to hunt--like wolves and other canines. Others, like goats, cows and horses, provided milk, hair and, finally, hides and meat. Managing all of these animals--or just tracking them--requires technology, knowledge and ways to preserve and convey information. So languages had to develop and evolve to meet the challenges. Tracking game has even been argued to be the origin of scientific inquiry, said Peter Richerson, professor emeritus (名誉退休的) in the Department of Environmental Science and Policy at the University of California, Davis. One of the signs that this happened is in petroglyphs (史前岩画) and other rock art left by ancient peoples. At first they were abstract, geometric patterns that are impossible to decipher (破译). Then they converge on one subject: animals. There have also been genetic changes in both humans and our animals. For the animals those changes developed because human bred them for specific traits, like a cow that gives more mill or a hen that lays more eggs. But this evolutionary influence works both ways. Dogs, for instance, might have been selectively taken in by humans who shared genes for more compassion, Those humans then prospered with the dogs help in hunting and securing their homes. What do we learn from the first paragraph about animals？

A.Animals have driven humanitys success.

B.Tool-making and language are uniquely human habits.

C.Employing wolves is uniquely human habit.

D.People live with animals everywhere.

Since the days of Aristotle, a search for universal principles has characterized the scientific enterprise. In some ways, this quest for commonalities defines science. Newton's laws of motion and Darwinian evolution each bind a host of different phenomena into a single explicatory framework.

(46)In physics, one approach takes this impulse for unification to its extreme, and seeks a theory of everything — a single generative equation for all we see. It is becoming less clear, however, that such a theory would be a simplification, given the proliferation of dimensions and universes that it might entail. Nonetheless, unification of sorts remains a major goal.

This tendency in the natural sciences has long been evident in the social sciences too. (47)Here, Darwinism seems to offer justification, for if all humans share common origins, it seems reasonable to suppose that cultural diversity could also be traced to more constrained beginnings. Just as the bewildering variety of human courtship rituals might all be considered to be forms of sexual selection, perhaps the world's languages, music, social and religious customs and even history are governed by universal features. (48)To filter out what is contingent and unique from what is shared might enable us to understand how complex cultural behaviour arose and what guides it in evolutionary or cognitive terms.

That, at least, is the hope. But a comparative study of linguistic traits published online today supplies a reality check. Russell Gray at the University of Auckland and his colleagues consider the evolution of grammars in the light of two previous attempts to find universality in language.

The most famous of these efforts was initiated by Noam Chomsky, who postulated that humans are born with an innate language-acquisition capacity that dictates a universal grammar. A few generative rules are then sufficient to unfold the entire fundamental structure of a language, which is why children can learn it so quickly.

(49)The second, by Joshua Greenberg, takes a more empirical approach to universality, identifying traits (particularly in word order) shared by many languages, which are considered to represent biases that result from cognitive constraints.

Gray and his colleagues have put them to the test by examining four family trees that between them represent more than 2,000 languages. (50) Chomsky’s grammar should show patterns of language change that are independent of the family tree or the pathway tracked through it, whereas Greenbergian universality predicts strong co-dependencies between particular types of word-order relations. Neither of these patterns is borne out by the analysis, suggesting that the structures of the languages are lineage-specific and not governed by universals.

[A] These issues cut right across traditional religious dogma. Many people cling to the belief that the origin of life required a unique divine act. But ff life on Earth is not unique, the case for a miraculous origin would be undermined. The discovery of even a humble bacterium on Mars, if it could be shown to have arisen independently from Earth life would support the view that life emerges naturally.

[B] Contrary to popular belief, speculation that we are not alone in the universe is as old as philosophy itself. The essential steps in the reasoning were based on the atomic theory of the ancient Greek philosopher Democritus. First, the laws of nature are universal. Second, there is nothing special or privileged about Earth. Finally, if something is possible, nature tends to make it happen. Philosophy is one thing, filling in the physical details is another. Although astronomers increasingly suspect that bio-friendly planets may be abundant in the universe, the chemical steps leading to life remain largely mysterious.

[C] There is, however, a contrary view-one that is gaining strength and directly challenges orthodox biology. It is that complexity can emerge spontaneously through a process of self-organization, ff matter and energy have an inbuilt tendency to amplify and channel organized complexity, the odds against the formation of life and the subsequent evolution of intelligence could be drastically shortened. The relevance of self- organization to biology remains hotly debated. It suggests, however, that although the universe as a whole may be dying, an opposite, progressive trend may also exist as a fundamental property of nature. The emergence of extraterrestrial life, particularly-intelligent life, is a key test for these rival paradigms.

[D] Similar reasoning applies to evolution. According to the orthodox view, Darwinian selection is utterly blind. Any impression that the transition from microbes to man represents progress is pure chauvinism of our part. The path of evolution is merely a random walk through the realm of possibilities. If this is right, there can be no directionality, no innate drive forward; in particular, no push toward consciousness and intelligence. Should Earth be struck by an asteroid, destroying all higher life -forms, intelligent beings, still less humanoids, would almost certainly not arise next time around.

[E] Traditionally, biologists believed that life is a freak-the result of a zillion - to - on& accidental concatenation of molecules. It follows that the likelihood of its happening again elsewhere in the cosmos is infinitesimal. This viewpoint de- rives from the second law of thermodynamics, which predicts that the universe is dying - slowly and inexorably degenerating toward a state of total chaos. Life stumbles across this trend only because it is a pure statistical luck.

[F] Historically, the Roman Catholic church regarded any discussion of alien life as heresy. Speculating about other inhabited worlds was one reason philosopher Giordano Bruno was burned at the stake in 1600. Belief that mankind has-a special relationship with God is central to the monotheistic religions. The existence of alien beings, especially if they were further advanced than humans intellectually and spiritually, would disrupt this cozy view.

[G] The discovery of life beyond earth would transform. not only our science but also our religions, our belief systems and our entire world view. For in a sense, the search for extraterrestrial life is really a search for ourselves - who we are and what our place is in the grand sweep of the cosmos.
