Many snakes make meals of frogs, however some seem like transferring their DNA into the amphibians as properly. A genetic evaluation means that parasites shared between snakes and frogs might facilitate the motion of genetic materials from one species to a different.

The “horizontal” switch of DNA between species was lengthy thought-about a uncommon occasion that occurred solely between microbes, however there’s rising proof that the method has been happening all around the tree of life.

Genetic sequences known as transposons – …
