This is how I believe platypuses were made. “No one knows how BovB travels between species, but Ivancevic and Adelson suspect that it might spread via blood-sucking parasites. They have found strong similarities between the BovB versions in leeches and zebrafish, bedbugs and snakes, ticks and lizards. By biting different hosts, parasites might help jumping genes to vault over the species barrier.” https://www.theatlantic.com/science/archive/2017/10/how-a-quarter-of-the-cow-genome-came-from-reptiles/542868/
By hopping between species, jumping genes have radically altered the course of animal evolution.
