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."
【C12】
选项
A、supported
B、alleged
C、rectified
D、described
答案
A
解析
上句提到该研究团队通过两种方式对他们的理论进行验证,本句顺接上句,说明验证的结果。A项supported表示“证实”,与tested“验证”形成呼应,代入句中表示结果表明他们的理论得到了很好的印证。B项alleged多指无真凭实据的断言,而上文正是作者所提供的依据。C项rectified表示“纠正”,但上下文并没有提及某理论出错并需要纠正。D项described侧重指描述细节,给读者或听众提供清晰的视觉图像,不符合语义。
