Mammals vary enormously in size, from weighing less than a penny to measuring more than three school buses in length. Some groups of mammals have become very large, such as elephants and whales,【C1】________others have always been small, like primates. A new theory developed by an international team, led by Jordan Okie,【C2】________an explanation for why and how【C3】________ groups of organisms are able to evolve【C4】________sizes, whereas others are not.
The research team【C5】________information on how quickly an individual animal grows and used it to【C6】________how large it may get【C7】________evolutionary time. Their research was published recently.
The new theory developed from the observation that some animals【C8】________fast and die young, while others take their time and mature much later. "Fast" animals-such as mice—breed very quickly, while humans mature slowly and are relatively older when they first have children. The theory【C9】________that those species that are relatively faster are more likely to evolve a large size quicker than slow species, and that their maximum size will be greater.
The research team tested their theory using the【C10】________ records of mammals over the last 70 million years, examining the maximum size of each mammal group【C11】________ that time, including whales, elephants, seals and primates. They found that their theory was very well【C12】________.
"Primates have evolved very slowly, and never got bigger than 1,000 pounds," said Okie, "The【C13】________was true of whales, which evolved their large size at the fastest【C14】________recorded."
The theory also makes predictions about the relative risks of extinction for large animals【C15】________small. The maximum size of an animal is limited by the rate of mortality in the【C16】________. Because larger animals【C17】________ breed less frequently than smaller animals,【C18】________the mortality rate doubles, the maximum size is predicted to be 16 times smaller.
"This is a really surprising【C19】________," said Okie. "It points to another reason why many of the large animals went【C20】________after the last Ice Age, and their high risk of extinction in modern environments."
【C6】
选项
A、display
B、predict
C、prove
D、discover
答案
B
解析
根据后面句子里的情态动词may可知,后面的内容谈论的是可能性,也就是说,单个个体能长得多大(how large it may get)是根据其成长时间的信息进行预测的,而不是研究得出的结论,故用B项predict“预测”。A项display“显示”、C项prove“证明”、D项discover“发现”均与may所表达的不确定语义矛盾,故排除。
