Simpleminded. You don't have any evidence to support this
conjecture.

I have mentioned it
here quite often.  

Yes, you've put forth this absurd conjecture many times.

Another benefit for many
species is that large predators don't survive
on such islands.  They cannot sustain a large
enough population to avoid in-breeding.

Incidental.

The Pleistocene is not much of a problem.
Ice ages produce glaciers, the evidence for
which is easy to see. But the onset of the
Pliocene (and if such a period should be so
defined at all) is much more uncertain.
See:http://en.wikipedia.org/wiki/Pliocene

" . . For most of North America, a different system (NALMA) is often
used that overlaps epoch boundaries:
* Blancan (4.75–1.806 mya)
* Hemphillian (9–4.75 mya); includes most of the Late Miocene
Other classification systems are used for California, Australia,
Japan and New Zealand. . . "

The Miocene/Pliocene transition is not at issue here. You are the
fool who stated that in respect of mass extinctions that "No such
event occurred in the last 10 Myr."

The supposed "Miocene/Pliocene transition" is
exactly the issue here. It would have been when
any such mass-extinction event would have taken
place.  Curiously, you can't identify it.

It's in the fossil record, you idiot.

The
reason for that is that NO such event did take
place.  

You know this how? References?

Chimps, gorillas, gibbons, and all other
primates (and other mammals) continued to survive
and prosper during and after this "event" just as
they had done before "it".

Yeah, so?
