Socotra islands, Yemen
The island is very isolated and through the process of speciation, a third of its plant life is found nowhere else on the planet. It has been described as the most alien-looking place on Earth.

Madagascar split from India around 88 million years ago, allowing plants and animals on the island to evolve in complete isolation. The island has been isolated for about 70 million years. Because of this, a very high proportion of the plants and animals are endemic, occurring nowhere else in the world. Consequently, Madagascar is a biodiversity hotspot in which over 80% of its plant and animal species are found nowhere else on Earth. These are dispersed across a variety of ecoregions, broadly divided into eastern and south-central rain forest, western dry forests, southern desert and spiny forest.
