No one supposes that our choicest productions have been produced by a single variation from the aboriginal stock.

One of the Duros' earliest colonization efforts was on Neimoidia, and over the millennia, the Neimoidians became a genetically distinct offshoot of the Duros race.

内莫第亚星是杜罗人最早殖民的行星之一，几千年之后，从杜罗人种族内基因变异产生的分支成为了内莫第亚人。

It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

Although solar scientists are still debating the detail, most believe that the magnetic field is generated in a shell of hot gas 35,000 kilometres thick and buried some 200,000 kilometres deep inside the sun.

这一举动变异电荷并产生太阳的磁场。一旦建立起来，磁场是强大到足以影响到运动中的带电气体，制造，反馈机制，它可以强烈放大或缩小的整体实力的竞争。

The trend is widely blamed on climate change caused by heat-trapping gases from burning fossil fuels, according to David Vaughan, a British Antarctic Survey scientist who landed by plane on the Wilkins ice bridge with two Reuters reporters in January.

英国籍南极洲调查科学家大卫沃恩表示，燃烧化石燃料所产生的温室气体导致气候变异，冰棚消融的趋势普遍被认为与此有关。沃恩於今年一月与两位路透社记者搭机登上威尔金斯冰桥。

"This is an evolutionary mechanism to generate new variation that can work faster than genetic mutation," added Kays, curator of mammals at the New York State Museum.

这是一种能比基因突变更快产生出变异的进化机制。

Elemental and isotopic data suggest that the chemical variations of the HT and LT lavas can not be explained by crystallization from a common parental magma.

元素和同位素数据表明，HT和LT熔岩的化学变异不是由一个共同母岩浆的结晶分异作用所产生。

It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation in the gene for melanosome production.

浅肤色的欧洲人和金斑马鱼类似，也是因为产生黑色素的基因发生了变异，从而使皮肤中的色素减少。

On Ray's first run of Tierra, random variation, death, and natural selection worked.

在雷对Tierra的首轮运行中，随机变异、死亡和自然选择都产生了效果。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
