David Quammen sets up a kind of scientific adventure story: the race between two men to explain the origin of species and how species vary so dramatically around the world. Islands feature prominently in the story as the laboratories in which evidence is found and must be interpreted into meaningful theory. All this is fraught with danger and suspense because the world around them is clinging to a biblical story that cannot account for facts. Now we see no problem with accepting the best scientific explanation of evolution.
That is… unless you are Ben Carson.
A brief video to orient us to the Wallace/Darwin race to formulate the theory of evolution from their respective studies on biogeography.
