问题     Language is one of the defining characters of our species, but we know virtually nothing about where it came from. "We have a lot of【C1】______, but we don’t have a lot of data, " admits Gary Marcus at New York University, U. S.
    The biological basis of【C2】______people speak, listen and comprehend—and how all of this mental equipment evolved—is【C3】______mysterious. Researchers can study animals to gain insights【C4】______many psychological abilities, but this is not possible with language as no animal【C5】______systems are anywhere near as【C6】______as ours.
    "【C7】______we know it’s【C8】______to humans and it evolved quickly, " says Marcus. We developed the skill after we split from our last common ancestor seven million years ago. 【C9】______he says, language probably【C10】______as recently as the last few hundred thousand years.
    It has been difficult to【C11】______data, but developmental studies could provide new【C12】______, he believes. So-called knockout studies, where mice are genetically modified to lack certain genes, have helped tease out the【C13】______of certain mental abilities and many genetic disorders. Though such experiments are not ethically【C14】______in humans, detailed observational studies on people with naturally-occurring genetic mutations(基因突变)related to language, could provide【C15】______data, says Marcus.
    A systematic collection of such studies would help us【C16】______which parts of language share an origin【C17】______other mental abilities and which parts have evolved【C18】______. For example, sufferers of William’s syndrome have difficulty【C19】______the world and understanding why things happen—yet they have near-normal linguistic abilities. On the other hand, autistic people have【C20】______understanding what other people have on their minds and this can also affect linguistic abilities.  [br] 【C10】
