Final answer:
The statement is true. Ardi, Lucy, and Nariokotome/Turkana boy are all bipedal fossils that have played a significant role in understanding the evolution of bipedalism in early hominins.
Step-by-step explanation:
True
The statement is true. Ardi, Lucy, and Nariokotome/Turkana boy are all bipedal fossils that have played a significant role in understanding the evolution of bipedalism in early hominins.
Ardi, or Ardipithecus ramidus, is an early hominin species discovered in Ethiopia. It is dated to about 4.4 MYA and is believed to be bipedal based on the position of the foramen magnum and other skeletal traits.
Lucy, or Australopithecus afarensis, is another important bipedal fossil. The discovery of her skeleton provided valuable insights into the anatomy and locomotion of early hominins.
Nariokotome/Turkana boy, also known as Homo erectus, is an early human species with clear evidence of bipedalism. The fossil of a nearly complete skeleton belonging to a young male was found in Kenya.
