Donald Johanson significantly altered our understanding of prehistory with his discovery of the Australopithecus afarensis fossil, famously named "Lucy," in 1974. This finding provided crucial evidence of bipedalism in early hominins, suggesting that walking on two legs predated the development of larger brain sizes. Johanson's work highlighted the complexity of human evolution and emphasized the importance of examining physical traits in understanding our ancestry. His discoveries shifted the focus from linear models of evolution to a more intricate web of human development.
