Maropeng is located near the Sterkfontein Caves in South Africa, a site significant for early human fossils including Mrs Ples, one of the most complete skulls of Australopithecus africanus. It serves as a hub for learning about human evolution in the area known as the Cradle of Humankind, where life first emerged 3.8 billion years ago and some of the earliest stone tools and evidence of fire use were discovered. The document discusses how humanity's development of tools, language, social structures and technology has both advanced our species and put increasing strain on the environment.
