The discovery of Lucy in 1974 gave insight into early hominin body form but lacked hand bones. Subsequent findings revealed Australopithecus afarensis hand morphology. New discoveries and research since then, including associated hand skeletons and archaeological evidence, have enhanced our understanding of hominin hand evolution and tool use. These advancements inform us about Lucy's tool-related abilities and dexterity, reshaping our interpretation of early human behavior. Recorded on 04/06/2024. (#39821)
