EDGE Species
Evolutionarily Distinct and Globally Endangered (EDGE) species represent a disproportionate amount of unique evolutionary history. They have few close relatives, are often the only surviving member of their genus, and sometimes the last surviving genus of their evolutionary family. Some EDGE species, such as elephants and pandas, are well known and already receive considerable conservation attention, but many others, such as the Yangtze River dolphin (the world’s rarest cetacean), the bumblebee bat (arguably the world’s smallest mammal) and the egg-laying long-beaked echidnas are highly threatened yet remain poorly understood and are frequently overlooked by existing conservation frameworks. Recent research indicates that 70% of the world’s most threatened and evolutionarily distinct mammal species are currently receiving little or no conservation attention. If these species are not highlighted and conserved we will not only lose many of the world’s unique species and a disproportionate amount of biodiversity, but we may also greatly reduce the potential for future evolution. The Zoological Society of London (ZSL) has launched a new global conservation initiative, the EDGE of Existence Programme to raise awareness and funds for the conservation of these species.

Famous quotes containing the words edge and/or species:
“As I came to the edge of the woods,
Thrush music—hark!
Now if it was dusk outside,
Inside it was dark.”
—Robert Frost (1874–1963)
“As kings are begotten and born like other men, it is to be presumed that they are of the human species; and perhaps, had they the same education, they might prove like other men. But, flattered from their cradles, their hearts are corrupted, and their heads are turned, so that they seem to be a species by themselves.... Flattery cannot be too strong for them; drunk with it from their infancy, like old drinkers, they require dreams.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
