Final answer:
Hands with long, curved fingers are not indicative of bipedal locomotion; instead, they suggest arboreal climbing behaviors. Bipedal adaptations include inward-angled knees, a small pelvis, and aligned toes, among others.
Step-by-step explanation:
The trait that is NOT reflective of bipedal locomotion is hands with long, curved fingers (option b). Bipedalism, which refers to walking upright on two legs, is characterized by specific anatomical adaptations. These include the foramen magnum located at the lower center of the skull to allow for an upright posture, knees angled inward towards the feet to better support weight during walking, a small pelvis with a smaller birth canal for efficient locomotion, the evolution of the arch in the foot, and the alignment of toes with the loss of an opposable big toe. Hands with long, curved fingers are typically associated with brachiation or tree-climbing behaviors, not with bipedalism.
