Description
The EDGE of Existence program uses a scientific framework to identify the world's most evolutionarily diverse and endangered species (EDGE), highlighting and protecting some of the most unique and beautiful species on the planet. EDGE species have few close relatives on the tree of life and are often very unusual in their appearance, life, behavior and genetic makeup. They represent a unique and irreplaceable part of the world's natural heritage, but an alarming number of them are threatened with extinction.
