Final answer:
Lucy, also known as AL 288-1, is a significant early hominin fossil that provided valuable insights into human evolution. Her well-preserved skeleton confirmed the bipedal nature of Australopithecus afarensis and helped scientists understand their locomotion, anatomy, and biology. Lucy's discovery also shed light on the evolution of intelligence, language, and culture.
Step-by-step explanation:
The significance of Lucy, commonly known as AL 288-1, lies in the fact that it is one of the most well-preserved and significant early hominin fossils ever discovered. Lucy belonged to the species Australopithecus afarensis, and her discovery provided valuable insights into human evolution. Lucy's skeleton, which was around 40% complete, helped scientists understand the locomotion, anatomy, and biology of early hominins. It confirmed the bipedal nature of Australopithecus afarensis and provided evidence for the transition from arboreal to terrestrial life. Lucy's discovery also had implications for our understanding of the evolution of intelligence, language, and culture. It showed that significant evolutionary changes in these areas occurred long after the emergence of bipedalism. Overall, Lucy's remains have revolutionized our understanding of human evolution and the origins of our species.
