When global warming finally came it stuck with a vengeance(异乎寻常地). In some regions temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America Europe and Asia. After driving many of the animals around them to near extinction, people were forced to abandon their old way of life for a radically new survival strategy that resulted in widespread starvation and disease. The adaptation was farming: the global-warming crisis that gave rise to it happened more than 10000 years ago.
As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future earth scientists are in the midst of a revolution in understanding how climate has changed in the past—and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have been combined to change the planet’s environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of years.
Most important scientists are beginning to realize that the climatic changes have had a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution from the dawn of primates(灵长目动物)some 65 million years ago to human ancestors rising up to walk on two legs from the huge expansion of the human brain to the rise of agriculture. Indeed the human history has not been merely touched by global climate change, though some scientists argue that there are some instances having been driven by it.
The new research has profound implications for he environmental summit in Rio. Among other things the findings demonstrate that dramatic climate changes is nothing new for planet Earth. The benign(宜人的)global environment that has existed over the past 10000 years—during which agricultural writing cities and most other features of civilization appeared—is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact the pattern of climate change in the past reveals that Earth’ s climate will almost certainly go through dramatic changes in the future—even without the influence of human activity.
Scientists believe that human evolution______.
选项
A、has seldom been accompanied by climatic changes
B、has exerted little influence on climatic changes
C、has largely been affected by climatic changes
D、has had a major impact on climatic changes
答案
C
解析
细节题。根据Scientists、human evolution将答案定位到第三段Mostimportant scientists are beginning to realize that the climatic changes have had a majorimpact on the evolution of the human species.New research now suggests that climateshifts have played a key role in nearly every significant turning point in human evolution,“最重要的是,科学家已经开始意识到气候的变化对人类进化有着重要影响。新的研究表明气候变化几乎在人类进化的每个重要转折点都起到关键的作用”。也就是说,科学家认为人类的进化深受气候变化的影响,C选项内容符合,所以答案选C。
