Have you ever seen an island on a lake? On an island? On a lake? On another island? Josh Calder has. Working in a dusty room of a library, he first saw one on a map, and has been fascinated with these “recursive islands” ever since. Songbud Alan Goffinksi takes us on a wild journey into these secret bullseyes hiding all over planet Earth. We learn from ecologist Elba Montes why recursive islands breed species found nowhere else on Earth, and thus are hotbeds of evolution.

Check out Josh Calder’s website for more island information and trivia.
