evidence: The island of Socotra represents around 95% of the landmass of the Socotra archipelago. It lies 380 kilometres (205 nautical miles) south of the Arabian Peninsula,[4] 240 km (130 nmi) east of Somalia. The island is geographically a part of Africa. The island is isolated and home to a high number of endemic species. Up to a third of its plant life is endemic. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth".[5] The island measures 132 km (82 mi) in length and 42 km (26 mi) across at its widest.[6] In 2008, Socotra was recognised as a UNESCO World Heritage Site.[7] [...] Geography [edit]Socotra is one of the most isolated landforms on Earth of continental origin (i.e. not of volcanic origin). The archipelago was once part of the supercontinent of Gondwana and detached during the Miocene epoch, in the same set of rifting events that opened the Gulf of Aden to its northwest.[28] Culturally and politically, the island is a part of Yemen, but geographically it belongs to Africa as it represents a continental fragment that is geologically linked to the continental African Somali Plate.[29]
