Two species of stickleback fish, both alike in dignityIn fair Japan, where we lay our scene
One was able to move to freshwater habitats, while the other couldn’t. New research out in Science implicates “jumping” genes as the cause.
These jumping genes, called transposable elements, discovered by Science Hero Barbara McClintock, make up half of our genome and up to 90% of corn’s, and they can copy and paste themselves willy-nilly into the genetic code. Randomly hopping through the genome is often harmful because it can disrupt otherwise functional genes, but this stickleback study gives us an example of the opposite occurring. ...
