以TPO31其中一篇閱讀篇章中的題目為例:
Geographic isolation also can proceed slowly, over great spans of time.
We find evidence of such extended events in the fossil record, which
affords glimpses into the breakup of formerly continuous environments.
For example, during past ice ages, glaciers advanced down through North
America and Europe and gradually cut off parts of populations from one
another. When the glaciers retreated, the separated populations of
plants and animals came into contact again. Some groups that had
descended from the same parent population were no longer
reproductively compatible- they had evolved into separate species.In
other groups, however, genetic divergences had not proceeded so far, and
the descendants could still interbreed- for them, reproductive isolation
was not completed, and so speciation had not occurred.
1. According to this paragraph, separation of subpopulations by glaciers
resulted in speciation in those groups of plants and animals that
(A) were reproductively isolated even after the glaciers disappeared
(B) had adjusted to the old conditions caused by the glaciers
(C) were able to survive being separated from their parent population
(D) had experienced some genetic divergences from their parent
population
根據段落, 由冰河所形成次級種群 (subpopulation)之分隔導致在動植物群落
中之物種形成(speciation) 為何
