African archaeology

Africa has the longest record of human habitation in the world. The first hominins emerged 6-7 million years ago, and among the earliest anatomically modern human skulls found so far were discovered at Omo Kibish.

European archaeology, as well as that of North Africa, is generally divided into the Stone Age (comprising the Lower Paleolithic, the Middle Paleolithic, the Upper Paleolithic, the Mesolithic, and the Neolithic), the Bronze Age, and the Iron Age. For Africa south of the Sahara, African archaeology is classified in a slightly different way, with the Paleolithic generally divided into the Early Stone Age, the Middle Stone Age, and the Later Stone Age. After these three stages come the Pastoral Neolithic, the Iron Age and then later historical periods. Africa's prehistory has been largely ignored, with the exception of research into early human evolution. However, it is overseen by the PanAfrican Archaeological Association, whose members consist of professional archaeologists from all over Africa. The Early Stone Age (ESA), which spanned from approximately 2.6 million years ago (mya) - 280,000 years ago (ya), describes a period in African prehistory in which the first stone tools were developed. Early sites along the East African Rift include Lomekwi in the Turkana Basin, Kenya, and Olduvai Gorge farther south in modern-day Tanzania. The earliest hominids were discovered in Ethiopia and titled Ardipithecus ramidus. The diverging species of hominin are known as australopithecines and were first discovered in Olduvai. Australopithecines and their fossils include Paranthropus boisei, the most famous being know and “Zinj” or “Nutcracker man” by Mary Leakey, the archaeologist who found it. Another older, famous australopithecine, related to those found at Olduvai Gorge but found approximately 2000 kilometers to the north east in the Awash Valley of Ethiopia, is Lucy, who was discovered by Donald Johanson and his team in 1974. The earliest relative dating for stone tool use was discovered in 2015, by Sonia Harmand, at Lomekwi 3 in West Turkana, Kenya with stone tools dating to 3.3 million years ago. Prior to this discovery, some of the oldest stone tools were found at Lokalalei 2C in West Turkana, where artifacts exhibiting knapping processes conducted by Australopithecus africanus date to about 2.34 million years ago, marking the beginning of the ESA. Incorporation of tools provided early hominins the ability to respond to changes more readily outside of the immediate needs of daily-life and extended adaptability behavioral patterns into long term trends experienced over generations. Around a million years later, Homo erectus evolved into a more advanced species and made tools known as the Acheulean handaxes. These handaxes were a multipurpose bifacial technology that remained unchanged for thousands of years. The technology demonstrates an increase in brain development and complexity in Homo erectus, as shown by the increased level of forethought and knowledge of material required for production of the tools. Homo erectus are also associated with the first instances of 'modern human living,' such as fire, 'modern emotions,' and art. The earliest evidence for hominins controlling fire is found in Wonderwerk Cave, South Africa. Along with their new technologies, they were also a part of the first 'Out of Africa' movement and spread to all parts of the world. This movement took place somewhere around 1.8-0.8 million years ago, where Homo erectus spread out from Africa and into Eurasia. One of the most notable Homo erectus skeletons ever found was that of Nariokotome Boy, who was found near Lake Turkana in Kenya, discovered by Richard Leakey and Kamoya Kimeu. Nariokotome Boy was a teenager when he died, and his skeleton exhibits the first evidence for caring in the archaeological record, because he was cared for through his debilitating scoliosis. Just recently discovered was a new addition to the line of human ancestors named Homo naledi. Found in Rising Star Cave in South Africa, Homo naledi is undated but has features of both primitive and modern humans. The Middle Stone Age (MSA), dating to roughly 280,000 to 40,000 years ago, is characterized by the continuation of hunter-gatherer lifestyles and, as more recently recognized, perhaps the origins of modern human behavior and cognition. Even though hominin species' brains were reorganized and modernized at a fast rate, the behavior of these hominins did not adapt quite as fast. This caused the hominin species to be quite primitive. African hunter-gatherers hunted larger mammals and relied on an assortment of edible plants, both in the grasslands that are now the Sahara desert, and the rain forests of Central Africa. Coastal peoples also subsisted on seafood and numerous middens indicate their diet. Homo sapiens appear for the first time in the archaeological record around 200,000 BCE in Africa. They soon developed a more advanced method of flint tool manufacture involving striking flakes from a prepared core. This permitted more control over the size and shape of finished tool and led to the development of composite tools, projectile points and scrapers, which could be hafted onto spears, arrows or handles. In turn, this technology permitted more efficient hunting such as that demonstrated by the Aterian industry. It was during the late Middle Pleistocene that many groups began to migrate away from eastern Africa, especially southward. Technological improvements such as Aterian methods and the development of new skills helped these people adapt to new landscapes.
