A PBS Eons video (9 m 24 s) discusses a well-known barrier between two of the islands of Indonesia--"an ancient line that is both real and...not real."

It was first noticed by Alfred Russel Wallace who also is known for independently conceiving of the theory of evolution by natural selection. This served as a kick-in-the-britches to Charles Darwin to publish his findings on the theory. Darwin had conceived the idea earlier, but was busy collecting more data in support of this revolutionary idea *. 

Wallace is also known as the father of biogeography.

* An HHMI BioInteractive (31 m 02 s) provides a "biography of Charles Darwin and Alfred Russel Wallace" tells the story of the "two independent discoveries of the natural origin of species." The video traverses the epic voyages and revolutionary insights...which changed biological science forever."
