Galapagos Natural Facts

The islands emerged about five million years ago, give or take a million, as a result of violent volcanic action. In geological terms, this should be considered a recent event.

As the young islands were cooling off, say, two million years later, some species gradually arrived. They were live organisms riding on "rafts of vegetation" from the shores of Central and South America. Unusual climatic events, like flooding, can take lots of vegetation rafts eventually to the ocean. Therefore, it is pure chance that allows a raft to eventually reach Galápagos. These early immigrants had to adapt to a peculiar new environment, and simply evolved -- slowly -- in a different direction from their continental ancestors. And, wonders of nature, they developed into species unique to the islands, with features not seen in their past ancestors.
