An island isolated for millions of years grew trees found nowhere else
Yemen's Socotra archipelago split from the African and Arabian mainlands millions of years ago and evolved in near-total isolation, earning it the nickname 'Galapagos of the Indian Ocean.' Today 37% of its roughly 825 plant species, 90% of its reptiles, and 95% of its land snails live nowhere else on Earth. Its most iconic resident, the umbrella-shaped dragon's blood tree, oozes a crimson resin and is thought to predate the island's very split from the continent.
