The Cradle of Humankind World Heritage Site is an area of outstanding universal value. Its complex of fossil-bearing caves contains a superbly preserved record of the stages in the evolution of humankind over the past 4-million years. It's the world's richest early hominin site and is home to around 40% of the world's known human-ancestor fossils. The area is also home to a diversity of birds, animals and plants, some of which are rare or endangered. http://www.thecradleofhumankind.net/
