托福阅读100个长难句实例剖析
原句案例:
Geographic isolation creates opportunities for new species to develop, but it does not necessarily lead to new species because speciation occurs only when the gene pool undergoes enough changes to establish reproductive barriers between the isolated population and its parent population.
词汇解释:
isolation: one group, person, or thing is separate from others.
speciation: speciation is the evolutionary process by which new biological species arise.
gene pool: the gene pool is the set of all genes, or genetic information, in any population, usually of a particular species.
