For example, in a study published last year in the Proceedings of the National Academy of Sciences a group of researchers looked at crustaceans (crabs, shrimps, woodlice and so on) over the past 550m years and found far more examples of groups of species evolving towards complexity than in the other direction.

举个例子，去年美国国家科学院公布的一项研究里，一群研究人员对生活在过去5.5亿年里的诸如螃蟹、虾、节肢动物有树虱之类的甲壳纲动物进行了研究。他们发现，更多的物种群体是朝着复杂而不是别的方向进化的。

In this study,an experimental modelwas developed and established with freshwater crayfish Cambarus clarkii to prolif-erate White Spot Syndrome Virusin vivo.The success and reliability ofthis model was confirmed by transmission electron microscopy,dot-blotand hybridization in situ etc.

本研究在阐明WSSV对常见淡水甲壳纲动物的侵染活性的同时，成功地建立了WSSV淡水克氏螯虾体内增殖模型，并通过电镜技术、核酸探针斑点杂交与原位杂交等手段证实所建立的增殖模型的可靠性。
