Question

Quizplus · Accepted Answer

Bramble and Lieberman's analysis shows that human beings are highly adapted for long-distance running, which is supported by multiple anatomical and physiological features such as longer legs, reduced toe length, and highly efficient cooling systems. While humans are capable of walking and climbing, their biomechanics and adaptations suggest that running is a key mode of locomotion for the species. There is no evidence to suggest that humans are well adapted for trucking.
