　　15. GWD-12-Q24 -Q27瓦格勒大陆漂移说在问世之初不被接受的原因

　　Years bore the advent of plate

　　tectonics― the widely accepted theory,

　　developed in the mid-1960’s, the holds

　　Line that the major features of Earth’s surface

　　(5) are created by the horizontal motions

　　of Earth’s outer shell, or lithosphere―

　　a similar theory was rejected by the

　　geological community. In 1912, Alfred

　　Wegener proposed, in a widely debated

　　(10) theory that came to be called continental

　　drift, that Earth’s continents were mobile.

　　To most geologists today, Wegener’s

　　The origin of Continents and Oceans

　　appears an impressive and prescient

　　(15) document, containing several of the

　　essential presumptions underlying plate

　　tectonics theory: the horizontal mobility

　　of pieces of Earth’s crust; the essential

　　difference between oceanic and conti-

　　(20) nental crust; and a causal connection

　　between horizontal displacements and

　　the formation of mountain chains. Yet

　　despite the considerable overlap

　　between Wegener’s concepts and the

　　(25) later widely embraced plate tectonics

　　theory, and despite the fact that conti-

　　nental drift theory presented a possible

　　solution to the problem of the origin of

　　mountains at a time when existing expla-

　　(30) nations were seriously in doubt, in its

　　day Wegener’s theory was rejected

　　by the vast majority of geologists. AW的理论遭到怀疑

　　Most geologists and many historians

　　today believe that Wegener’s theory

　　(35) was rejected because of its lack of an

　　adequate mechanical basis. Stephen

　　Jay Gould, for example, argues that

　　continental drift theory was rejected

　　because it did not explain how continents

　　(40) could move through an apparently solid

　　oceanic floor. However, as Anthony

　　Hallam has pointed out, many scientific

　　phenomena, such as the ice ages, have

　　been accepted bore they could be fully

　　(45) explained. The most likely cause for the

　　rejection of continental drift―a cause

　　that has been largely ignored because

　　we consider Wegener’s theory to have

　　been validated by the theory of plate

　　(50) tectonics―is the nature of the evidence

　　that was put forward to support it. Most

　　of Wegener’s evidence consisted of

　　homologies—similarities of patterns and

　　forms based on direct observations of

　　(55) rocks in the field, supported by the use

　　of hammers, hand lenses, and field note-

　　books. In contrast, the data supporting

　　plate tectonics were impressively

　　geophysical—instrumental determinations

　　(60) of the physical properties of Earth gar-

　　nered through the use of seismographs,

　　magnetometers, and computers.被怀疑的原因
