Hi!
Interestingly, in Boris' first site reference, we see several branches go out from the origin in East Central Africa and come to a stop.
While all the other branches were doing their thing, these particular end points were just sitting there, cooking!
And making variations on a theme, as you suggest?
Just to set the record straight.
The first sight reference was posted by Bob W, not me. Though our names start with the same letter :).
