Which of the following is believed to be a selective pressure that favoured the emergence of bipedal locomotion in hominoids? a. Upright posture reduced the amount of skin surface exposed to the sun. b. Upright posture allowed individuals to travel long distances more rapidly. c. Upright posture allowed early hominins to hunt animals more effectively. d. All of the above.

Which of the following has been suggested to have selected for bipedalism in the hominin clade? a. increasing parasite load, which promoted long-distance migration to escape from parasites. b. predators evolved faster movements, selecting for the ability of hominins to run faster. c. Transformation of forests into open savanna vegetation due to a drying climate; bipedalism was favored in open environments. d. Bipedalism allowed more efficient catching of fish and other aquatic organisms, which provided a plentiful source of protein. e. Bipedalism allowed the reaching of fruits that occurred higher on shrub and tree branches, helping to increase survival in environments where the diet was poor.

What most likely influenced the evolution of bipedalism? a. Humans wanted to stand erect in order to run faster. b. Bipedalism facilitates tool use. c. Bipedalism facilitates sexual intercourse. d. An upright stance exposes more of the body to the sun, and vitamin D production requires sunlight. e. All of these are correct.
Anatomical changes in hominins that are indicative of habitual bipedal locomotion include: a. feet with opposable big toes for grasping b. all of the answers are correct c. increased length of arms relative to legs d. shortening and broadening of the pelvis
