Th abstract indicates a plausible idea, but of course it's "all in the details" whether much new is added. The RAO idea has been around for quite some time, and does have lots of supporters.

A side path on the RAO idea is sometimes called the "Eve Theory" which postulates that we should be able to find a "single mother" (Eve of course) who was the "first human." Few credible people have meant "Eve" to mean a single "person," but quite a few less thoughtful ones have believed that's what they meant. Finding a single area in which traceable ancestors first appeared was all that was really intended by those who first used the term.

There's still much debate about whether there was a single place of origin, or several. Even if the genetic origin of humans was a more "dispersed" phenomenon, it still seems likely that it was localized since access to precursor gene pool(s) would likely be necessary to establishment of a surviving new line. The "sport" genetic deviation may result in new and helpful characteristics, but seldom survives on it's own unless it can recall - and be mixed back in with - the other characteristics that permitted survival up to the time of it's appearance.

Maybe...
