New research shows plants can shuffle and paste gene pieces to generate genetic diversity
...There is mounting evidence, however, that TEs help organisms
evolve by making it easier to generate the sort of genetic novelty that is necessary for them to cope with a changing world. Thus, instead of being beasts of burden, Pack-MULEs may serve rice as a tool of evolutionary change. ...
