knowing what gene drives are is crucial to understand the most important and powerful biotechnology yet.

Gene drives work in mice:

In a paper in Nature, biologists demonstrate that gene drive technology also works — at least up to a point — in a mammal: the mouse. Their findings highlight the potential, but also the significant limitations, of putting gene drives to work in the real world. For at least some time to come, these kinds of “active genetics” technologies may be more useful as laboratory tools than as instruments for remaking nature.
