问题    Modern biology is based on several unifying themes, such as the cell theory, genetics and inheritance, Francis Crick’s central dogma of information flow, and Darwin and Wallace’s theory of evolution by natural selection. In this first unit we will examine these themes and the nature of science.
   The ancient Greek philosopher Anaxiamander (611- 547 B. C. ) and the Roman philosopher Lucretius (99 – 55 B. C. ) coined the concept that all living things were related and that they had changed over time. The classical science of their time was observational rather than experimental. Another ancient Greek philosopher Aristotle, developed his Scala Naturae, or Ladder of Life, to explain his concept of the advancement of living things from inanimate matter to plants, then animals and finally man. This concept of man as the "crown of creation" still plagues modern evolutionary biologists.
   Post-Aristotlean "scientists" were constrained by the prevailing thought patterns of the Middle Ages—the inerrancy of the biblical book of Genesis and the special creation of the world in a literal six days of the 24-hour variety. Archbishop James Ussher of Ireland, in the late 1600’s calculated the age of the earth based on the geneologies from Adam and Eve listed in the biblical book of Genesis. According to Ussher’s calculations, the earth was formed on October 22, 4004 B. C. These calculations were part of Ussher’s book, History of the World. The chronology he developed was taken as factual, and was even printed in the front pages of Bibles. Ussher’s ideas were readily accepted, in part because they posed no threat to the social order of the times; comfortable ideas that would not upset the linked apple carts of church and state.
   Often new ideas must "come out of left field", appearing as wild notions, but in many cases prompting investigation which may later reveal the "truth". Ussher’s ideas were comfortable, the Bible was viewed as correct, therefore the earth must be only 5, 000 years old.
   Geologists had for some time doubted the "truth" of a 5, 000 year old earth. Leonardo da Vinci (painter of the Last Supper, and the Mona Lisa, architect and engineer) calculated the sedimentation rates in the Po River of Italy. Da Vinci concluded it took 200, 000 years to form some nearby rock deposits. Galileo, convicted heretic for his contention that the Earth was not the center of the Universe, studied fossils (evidence of past life) and concluded that they were real and not inanimate artifacts. James Hutton, regarded as the father of modern geology, developed the Theory of Uniformitarianism, the basis of modern geology and paleontology. According to Hutton’s work, certain geological processes operated in the past in much the same fashion as they do today, with minor exceptions of rates, etc. Thus many geological structures and processes cannot be explained if the earth was only a mere 5, 000 years old.
Unlike Galileo, Ussher’s concept was accepted by both the church and state of his time because______.
选项 A、his ideas would not weaken the power of the church and state
B、he calculated the age of the earth accurately
C、he was not constrained by the prevailing thought pattern of the Middle Ages
D、his calculation was printed in the front pages of Bibles
答案A
解析 根据第三段、第四段和第五段，Galileo因为认为地球不是宇宙的中心而被那个时代的教会和政府打入监牢；James Ussher的理论因为是基于《圣经》的《创世纪》，没有威胁到教会和政府的权力和利益，因而能为当时的教会和政府所接受。
