Scanning Life
Life would be simpler if all species wore name tags.Hebert,an evolutionary biologist at Biodiversity Institute of Ontario,described the diversity of life as a “harsh burden” to biologists,and proceeded to suggest some relief:Every species on Earth could be assigned a simple DNA bar code so that it would be easy to tell them apart.
The bar code Hebert suggested is part of a gene called CO1 that every multicellular organism has.But there is enough variance in its sequence that two species rarely have the exact same one.Such differences in a gene are readily scanned by machine even when the animals themselves might confound an expert.The technique has commercial and scientific promise.Mislabeling of fish on menus is rampant,it turns out.
Bar coding has spread throughout the animal kingdom and even to plants an fungi.With a seal of approval from the United Nations,which has declared 2010 the International Year of Biodiversity researchers in 25 countries are now aiming to bar code 500,000 species-of the 1.7 million already named on Earth-by 2015.Hebert is convinced that any species humans encounter frequently will be bar coded by 2025.
Some biologists dislike this grand plan:they worry that bar coding,which is best at identifying species that have already been described,will steal scarce research dollars from the more valuable work of describing unnamed species.Hebert sees the technique as popularizing biodiversity at a time when it is vanishing fast.

生活的归纳
生活会更简单,如果所有物种穿名牌.赫伯特,一在安大略生物多样性研究所的进化生物学家,描述为“苛刻负担”生物学家对生命的多样性,进而提出了一些救济:地球上每一个物种可以被指定一个简单的DNA条形码,使其容易告诉他们分开.
条码埃贝尔建议是一个名为CO1基因,每个基因的多细胞生物体的一部分.但是,在它的序列足够的方差,两个物种很少有完全相同的.这种差异在一个基因可随时由机器扫描甚至当动物本身可能混淆的专家.该技术具有商业和科学的承诺.对菜单鱼类商品标示猖獗,原来.
条码已蔓延整个动物王国,甚至植物的真菌.随着来自联合国,联合国已宣布2010年为国际生物多样性研究人员在25个国家今年已旨在条码500,000种,170万已命名的批准印章地球到2015年.赫伯特相信,任何物种人类经常遇到的酒吧,到2025年将编码.
有些生物学家不喜欢这个宏伟的计划:他们担心,条码,这是最好在确定已经被描述的物种,将窃取的不知名物种的描述更有价值的工作缺乏研究经费.赫伯特认为,作为一次普及生物多样性消失时,快速的技术.
