Good try. However, most of the "jumping genes" you reference here do
their jumping within a single individual, i.e. from one place in the
genome to another place in the same genome. The interesting thing is
that humans and chimps share a very similar pattern of jumping gene
insertions, some but not all of which is also shared with gorillas, and
a lesser number with orangutans, and a lesser number with gibbons, etc.

And humans/chimps are not related merely by jumping genes, but by the
entire genome, including the functional parts. So unless the entire
genome has been replaced in one species or another, your explanation
isn't credible.- Hide quoted text -

John you could not possibly be any vageur if you tried.

"Jumping genes"?
"Single individual"?
"Transposons shared with chimps"?
"Similar Jump patter"?

If you have questions, ask them. Those aren't questions. Do you know what transposons are? Do you know how they work? Very simply, they are copied from one location in the genome into another location. That's called an insertion. Each insertion happens in a single individual, and may spread through ordinary reproduction (perhaps aided by selection, perhaps merely by drift) through the entire population. We share particular insertions -- that is, transposons in particular locations in the genome -- with chimps, somewhat fewer insertions shared with gorillas, and so on.

Lets assume that transposons occur.

How could 2 species have similar "jump patterns"?

By inheriting them from their common ancestor, of course. Any insertion that happened in the common ancestor of chimps and humans would be retained in its descendants.
