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.

歐洲變異老鼠百毒不侵

???????據英國廣播公司報道，科學家稱，歐洲一些國家的普通家鼠發生基因變異百毒不侵。

???????德國和西班牙的老鼠與阿爾及利亞老鼠品種共同繁育，進化出此番特質。

???????研究人員說，這種不同物種之間的基因轉移是非常罕見的，只在植物和細菌中比較常見。

???????研究人員擔心，這種罕見的迅速進化將會讓這種對所有化學類鼠藥免疫的新一代老鼠到處肆虐。
