Leading A Double Life Affairs, Daphne major is a volcanic island, 120 meters in elevation, in the Galapagos islands. How does the habitat (environment) differ between the islands? interpretation of the phylogenetic tree in the illustration? The Galpagos islands are considered to be "young" islands. The island is tree-less, eroded by sea, and looks bowl-like. Their pioneering studies documented natural selection in real time and revealed clues about how 13 distinct finch species arose from a single ancestral population that migrated from the mainland 2 million to 3 million years ago.
