- londons_explore 3y agoMany natural barriers one can walk around the end of. And other natural barriers might only be temporary (eg. rivers move, fire damaged areas regrow). But some natural barriers (eg. the ocean) are pretty impenetrable, and those have really shaped evolution (eg. kangaroos in australia).
