Joining FATE in the pantheon of conservation acronyms, EDGE stands for Evolutionarily Distinct and Globally Endangered. It is the focus of the EDGE of Existence project, “saving the world’s most extraordinary species”:
“The EDGE of Existence programme is the only global conservation initiative to focus specifically on threatened species that represent a significant amount of unique evolutionary history.
Using a scientific framework to identify the world’s most Evolutionarily Distinct and Globally Endangered (EDGE) species, the EDGE of Existence programme highlights and protects some of the weirdest and most wonderful species on the planet. EDGE species have few close relatives on the tree of life and are often extremely unusual in the way they look, live and behave, as well as in their genetic make-up. They represent a unique and irreplaceable part of the world’s natural heritage, yet an alarming proportion are currently sliding silently towards extinction unnoticed.”
EDGE species are on the edge, so EDGE is clear pre hoc.
