Final answer:
The statement about Lucy being part of the group called "Homo" is false. Lucy is from the species Australopithecus afarensis, which is an earlier ancestor and not part of the Homo genus that includes modern humans.
Step-by-step explanation:
The statement that the famous fossil "Lucy" belongs to a group of Hominini that is called "Homo" is false. Lucy is a member of the species Australopithecus afarensis, which predates the genus Homo. The genus Homo includes modern humans (Homo sapiens) and our close extinct relatives, such as Homo erectus and Homo neanderthalensis. Lucy is known for her significant role in our understanding of human evolution because of her well-preserved fossil, which showed evidence of bipedalism, a crucial step in human evolution. Lucy's discovery in Ethiopia in 1974 by paleoanthropologist Donald Johanson provided insight into early hominins, showcasing several evolutionary traits such as an upright walking posture, which are hallmark features of the hominin lineage including Australopithecus, Homo habilis, and Homo erectus. Despite similarities with modern humans, Lucy's species has distinct differences from the Homo group, such as a smaller brain and a more protruding jaw, which are evident when comparing Australopithecine and modern human skulls.
