Scientists say that some European house mice have developed resistance to the strongest poisons, BBC reported.
German and Spanish mice have rapidly evolved the trait by breeding with an Algerian species from which they had been separated for over a million years.
The researchers say this type of gene transfer between different species is highly unusual and normally found in plants and bacteria.
They are concerned that this rare form of rapid evolution could herald the spread of new generations of rodents resistant to almost any form of chemical pest control.

欧洲变异老鼠百毒不侵
据英国广播公司报道,科学家称,欧洲一些国家的普通家鼠发生基因变异百毒不侵。
德国和西班牙的老鼠与阿尔及利亚老鼠品种共同繁育,进化出此番特质。
研究人员说,这种不同物种之间的基因转移是非常罕见的,只在植物和细菌中比较常见。
研究人员担心,这种罕见的迅速进化将会让这种对所有化学类鼠药免疫的新一代老鼠到处肆虐。
