Transposable elements are not merely a successful prediction of
common descent, they are a powerful exhibit of dysteleology—the
lack of design. We can hardly imagine that god would have
installed these not very useful DNA segments at the same place
in cousin species. As theological evolutionists explain,
transposable elements are an example where the design hypothesis
fails and there really is no other explanation aside from common
descent. The IFF statement In other words, this is not the usual
case of IF theory X is TRUE, then we should observe Y. Instead,
this is a case of IF AND ONLY IF theory X is TRUE, then we
should observe Y. Not only does common descent explain
transposable elements, but only common descent explains
transposable elements. The IF AND ONLY IF statement, also known
as an IFF statement, is different from the usual IF statement in
some important ways. First, given IF X THEN Y, it is not true
that IF Y THEN X. In other words, a successful prediction does
not mean the theory is true. That i
