So… why aren’t there any frogs in the Galapagos Islands? I don’t know if Galapagos tour visitors ever wonder about this, but Charles Darwin did find the particular fact quite unnerving… especially since he was ready to study theology for who knows how long and perhaps even become a priest. Could he still do this, upon noticing that the Galapagos Islands had no frogs? There were enough marsh and lake habitats to support amphibian life… why, and this was the question, did God not put amphibians in them!?
There may very well be an interpretable answer to this in the Bible, actually explaining why God decided the Galapagos, out of all places, did not deserve frogs. But Darwin thought, perhaps, there was a simpler solution, much less divine, and much more logical, as to why the Galapagos Islands did not record amphibians. His basic conclusion was: they never got there. While the other animals found in the archipelago did… frogs didn’t. They actually couldn’t… they would die in the oceanic salt water.
So putting two and two together, this could feasibly suggest that, at some point, the Galapagos Islands had no living creatures on them, and that the only living creatures Darwin found somehow traveled to the islands by their own means. No divine intervention… just plain transportation on large rafts of vegetation.
Darwin’s absence-of-frogs observation may have been one of the earliest suggestions of a land without animals… past the Seventh Day of Creation, that is. “This could be big… very big.”
