What are the main aspects of bipedal locomotion?
Major morphological features diagnostic (i.e., informative) of bipedalism include: the presence of a bicondylar angle, or valgus knee; a more inferiorly placed foramen magnum; the presence of a reduced or nonopposable big toe; a higher arch on the foot; a more posterior orientation of the anterior portion of the iliac …
What is bipedal locomotion?
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped /ˈbaɪpɛd/, meaning ‘two feet’ (from Latin bis ‘double’ and pes ‘foot’).
What are the organs involved in bipedal locomotion?
groups involved in bipedal locomotion include the gluteals and front and back muscle groups of the thigh.

Which of the following limb features are associated with bipedalism?
Which of these features are associated with bipedalism as seen in humans? Correct Answer(s): short ilium – The short ilium of the pelvis is important in providing stability for bipedal motion.
What is bipedal quizlet?
Walking on 2 legs. A defining feature of hominids.
What are the seven steps of bipedalism?
Terms in this set (6)
- Foramen Magnum. A large opening at the base of the skull through which the brain connects to the spinal cord.
- S-shaped spine. Brings the body’s centre of mass directly over the feet, allowing upright stance and movement as well as acting as a shock-absorber.
- Pelvis. …
- Valgus knee.
- Arched foot.
- Big toe.
Why is bipedalism a more efficient way to travel?
Human bipedalism is very efficient at normal walking speeds, because forward motion results from gravity swinging each leg forward like a pendulum. The walking biped recaptures this forward momentum by slowing the swinging leg before footfall.
