🔑 Key Concepts & Definitions

• 3-4 million years ago: The period during which Australopithecus existed, marking an early stage in human evolution.
• Lived in Africa: Australopithecus fossils have been primarily found in Africa, indicating their geographic origin.
• Partially upright walking: Australopithecus exhibited some degree of bipedalism, walking upright but not fully adapted to modern human locomotion.
• Partially arboreal: They still spent significant time in trees, indicating a lifestyle that combined walking on the ground with climbing.
• Various 'upright' hypotheses: Different scientific theories attempt to explain the evolution of upright walking in Australopithecus (see section 7).
• Famous specimen: Lucy: A well-preserved Australopithecus afarensis fossil discovered in Ethiopia, providing critical evidence of early bipedalism.
