The Science paper, by developmental biologist Ethan Bier and his student Valentino Gantz at the University of California, San Diego, used CRISPR to insert a modification into genes on both chromosomes in a pair, so that when the flies bred, they would pass the modification on to practically all of their offspring.

This research, by contrast, suggests that rapid evolution of a complex social behavior like pair bonding can occur by changing the expression of just one gene, he says.
