Final answer:
Early Homo species such as Homo erectus are most like humans in terms of long distance running. They had a broader pelvis, longer legs, and arched feet, which allowed for efficient running over long distances.
Step-by-step explanation:
Modern Homo sapiens, or humans, are most like early Homo species such as Homo erectus in terms of long distance running. These early Homo species had anatomical adaptations that made them efficient at bipedal locomotion, similar to modern humans. They had a broader pelvis, longer legs, and arched feet, which allowed for efficient running over long distances. However, they still had some physical differences, such as bigger jaws and teeth, a sloping forehead, and a relatively small brain.
