题目信息

The ability to analyze genomes - sequences of DNA - has grown more and more sophisticated. Scientists are able to examine the biological past in finer detail and with greater accuracy. A new analysis of the genetic links between early humans and chimpanzees has led to a hypothesis that the two species diverged more recently than previous estimates indicated. This gives credence to a very startling new theory: the ancestors of humans and chimpanzees might have hybridized to produce the lineage from which modern humans eventually developed.

What can be inferred from the statements above?

A:Hybridized species combine the best of both lineages.

B:Political and religious pressures will affect the course of future research.

C:Future research will enable scientists to determine the exact characteristics of this hybrid ancestor of modern man.

D:Earlier genome analysis established genetic links between early humans and chimpanzees.

E:Human DNA is more complex than that of chimpanzees.

正确答案： D:Earlier genome analysis established genetic links between early humans and chimpanzees.

选D的原因是这句话A new analysis of the genetic links between early humans and chimpanzees has led to a hypothesis that the two species diverged more recently than previous estimates indicated.说这个新的分析做出了一个假说认为这两个物种更加的分离相比于原先估计的，就证明在这个分析之前已经有关于两个物种的研究了，现在这个只是进一步深化了而已
