Nature is always on the go, and often, so are the parts of the world. You hear a rumble, and wherever you were has decided to take off on an adventure. Sometimes the trip is short, sometimes lengthy. No telling.
As illustrated, sometimes one part of the RFamily is split up, just like the landscape. Everybody just has to make the best of things. Whereas the whole family had a developed “look” when the rift occurred, it doesn’t mean that things will stay that way. In less than no time, both sections of the family may morph. Communities have a way of transforming that can take our breath away. Adaptation: your Inner Rhino is flexible, but not predictable. Same thing with your Outer Rhino!
Pretty neat, when you think about it.
By the way, bear in mind that in the picture, there is no telling which part of the landscape has set sail. One of those point-of-view puzzlers.
