Hybridization Partially Restores Vision in Cavefish, NYU Study Finds

Hybridizing blind cave fish from different cave populations can partially restore the vision of their offspring, biologists at New York University have found. The study suggests that genetic engineering can override, at least in part, half a million years of evolutionary change in one generation.

The study examined four populations of blind cavefish from different caves, depicted with arrows, in Mexico.
