Second, explore what is known about the origins of early hominid bipedalism by answering the following: What is the traditional explanation for the development of the bipedal locomotion adaptation in hominids. How do the following fossils support or challenge this explanation?
• "Lucy" Australopithecus afarensis (figure 5.5 in our textbook)
• "Ardi" Ardipithecus ramidus (figure 5.3 in our textbook)
Third, explain why endurance running may be an important adaptation for later hominid species such as Homo erectus. What adaptations are necessary for hominin endurance running to be possible? According to some scholars cited in our textbook, when and why did endurance running develop?

Finally, describe something you thought was interesting about both Neandertal cultural practices and Paleolithic cultural practices (of anatomically modern humans).
