'Super' mouse evolves resistance to most poisons

The mice acquired the trait through breeding with an Algerian species.

The mice acquired the trait through breeding with an Algerian species.


閱讀難度:

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.
