Plenty evidence for the genetic degradation of humanity though. You need look no further than your local evangelicals
That's specifically due to weird mating practices of first cousins, uncles and nieces and even siblings reproducing with each other. Evangelicals are weird.
There is degradation overall for several factors. eg Natural selection is largely not a factor anymore with us and people born with genetic faults who normally would not have lived or at least long enough to reproduce, but now live through the magic of modern medicine/science and can pass on those faulty genes.
edit: Actually, I think it was you who posted the Adam Eyre-Walker paper years ago on humans' high rate of harmful genetic mutations over the generations? Maybe someone else.
