We know that speciation is caused when a single species/group spilts and no longer mates. This can be caused by something as simple as river separating the two populations or one species does not recognize the "mating dance" of the other species. Now how changes occur at levels about genus, NO, we have no direct evidence of that ever happening, especially by mutation.

How long is this supposed to take?

While that's generally true, without getting into the particulars here, there are some problems with the mating/not mating definition of species. There are still some fuzzy areas around our definitions.
