Sri Lanka, an island nation in the Indian Ocean, is a biodiversity hotspot. Despite its small size, the country has a high level of endemism, with many species of flora and wildlife found nowhere else on Earth. This amazing phenomenon reflects the island's unique evolutionary history, various habitats, and complex climate conditions. Sri Lanka's endemism is heavily influenced by its geographical isolation and diverse geography. The island's separation from the Indian subcontinent around 20 million years ago allowed its ecosystems to evolve independently, resulting in the emergence of distinct species. Geographic Isolation : Sri Lanka's island status has made it a perfect laboratory for evolution. Species that came on the island experienced distinct environmental stresses than their mainland counterparts, resulting in divergent evolutionary pathways. Sri Lanka's topography is diverse, with lowland rainforests, highland forests, arid zones, and coastal ecosyst...
