A Visit to California’s Version of the Galapagos Islands.
These islands—which seem to rise from the sea like a string of floating mountains—have never been part of the mainland. During the last ice age they were only five miles from shore, allowing mammals to raft there on debris and to then evolve in a relatively protected arena. Today the islands are home to 150 species found nowhere else on Earth.
