So even though the sequence helps with jumping activity, losing it gives the jumping gene an advantage in primates by allowing it to escape repression by ZNF93.
Maria Nilsson and colleagues at West-falische Wilhelms Universitat Munster in Germany compared jumping genes in the seven main branches of marsupials.
In 1982 Allan Spradling and Gerry Rubin showed that a jumping gene called 'P-element' can be used to genetically transform fruitflies by carrying any gene on these P-elements and putting them into the fruitflies.
Rare striped roses such as the mediaeval red-and-white striped Rosa mundii, and the modern red-and-yellow striped `Harry Wheatcroft' are well known examples of jumping genes that modify genes for petal pigment.

The researchers recognized L1 retrotransposons -- distinguishing them from the vast amount of fixed "fossil" transposable elements that litter the genome -- because these actively jumping genes are human specific and almost exactly the same in sequence from one person to another.
Jumping genes, pieces of DNA that replicate and insert themselves into a host's genome, have been actively shaping human and other primate evolution, researchers said February 14.
The researchers aligned these mobile elements to the human genome, and found that close to 100 of the human genome's non-coding elements are derived from these jumping genes.
