It's bollocks, to put it bluntly.
First of all, migration of organisms to new land masses is well documented in the literature, if anyone cares to exercise the requisite diligent effort. This includes primates. Second, acquisition of novel features post-migration is also well documented in the literature - island gigantism being merely the best documented example. For that matter, organisms have demonstrably engaged in adaptive radiation and rampant speciation whilst still living side by side - see, for example, the Lake Victoria Cichlid Superflock, which is known to have radiated from one well-defined (and identified) common ancestor 12,400 years ago, into the species flock currently observed (though Cichlids are particularly well suited to this process, which is why the process has also been documented for other Rift lakes, such as Malawi and Tanganyika).
Oh, as for the idea that there's no fossil evidence for anything resembling a Pongid in Africa, that's bullshit. You can download, for free, an entire book devoted to Tertiary African Pongidae, published by Yale University way back in 1969. Enjoy.
