“The introduction of any new technology is going to have all sorts of speed bumps,” says Mr Benner.

班纳表示：“任何新技术出炉后都要经历各种路障阻碍”。

"This is the first example of an artificial chemical system capable of Darwinian evolution," says Steven Benner, the research leader.

“这是首例有能力进行达尔文式进化的人造化学体系，”研究领导者史蒂文·伯纳(Steven Benner)说。

Benner said artificial DNA molecules are used as medical tools - for example to help doctors monitor the level of HIV in a patient's blood.

BENNER说人工DNA分子被当作医学工具来使用——比如说，可以帮助医生监测病人血液中的HIV级别。

"Chemists think this is an exceptional result, and therefore chemists will, like Carl Sagan says, require exceptional evidence to prove it," Benner said.

“化学家们认为这是一次例外结果，因此正如Carl Sagan说的那样，化学家们需要例外的证据来证明这一结果，”Benner说。

Grabher, 2002b. According to Benner 2003, such communities have played an important role for individuals in Silicon Valley in acquiring and maintaining specialized competencies.

Benner认为，这样的社区在硅谷获得和维持其专业化能力单独扮演着重要的角色。

Mark Benner, a spokesman for the agency in suburban Detroit, declined to confirm the figures, citing a policy to not comment on "forced adjustments due to scaled-down client work."

该机构在底特律的新闻发言人，马克·班纳，拒绝了对这一数据进行证实，他引用了一项政策，表示对“由于客户规模下降而被迫采取的调整措施”不予评价。
