Yep, I’ve heard of it. On the list of flightless species from DV.

OK. Island biogeography. Species island hop to recover from blighted areas. It happened all over the Pacific Islands during WW-II. But here is the difference, the much larger gaps between islands near Aldabra means that subspecies have time to form between island-hopping events.

And in this case a similar environment caused the same subspecies to be created twice, in parallel.
