development of early humans, termed hominids, is a fascinating journey that begins several million years ago with species that bear both similarities and significant differences to modern humans. The journey encompasses the evolution of various species, including australopithecines, the genus Homo, neanderthals, and ultimately Homo sapiens.\n\n4 million years ago, the world looked reasonably similar to how it does today. The dinosaurs were long gone, the continents were more or less as we know them now, and the world was full of plants and animals, many of which we’d recognise today.\n\nAmong these were the australopithecines. These were a species of primate that developed in Africa, and were the first animals to display many traits that we’d now recognise as human. One of these was bipedalism (walking on two legs), which is thought to have developed as these creatures stopped living in trees.\n\n![Graph](image://d268bced-abd5-4045-aaa8-84de266d38c9 \"Reconstruction of an australopithecine.
