Name the structure at the base of the skull where the spinal cord connects to the brain.

• Cranium

• Mandible

• Foramen magnum

Describe the trend in the feature from the previous question as we move from earlier hominins to modern humans.

• It gets larger

• It moves from the rear of the skull to a more central position

• It moves from the centre of the skull to the rear of the skull

• It gets smaller

Name the skull structures that are more prominent in apes compared to modern humans.

• Foramen magnum, valgus angle and sagittal crest

• Zygomatic arch, mandible and nuchal crest

• Nuchal crest, humerus and chin

• Sagittal crest, cranium capacity and nuchal crest

When the upper and lower jaw sticks out from the face, this is called...

• Prognathism

• Maxillary angle

• Valgus angle

• Cranium capacity

Describe the trend in the feature described in the question above as we move from earlier hominins to modern humans.

• It decreases

• It stays the same

• It increases

Many skull features change as we move from earlier hominins to modern humans. What was the main reason for these changes?

• Hominins moved from being arboreal to living on the ground

• Hominins became bipedal

• Hominins diet changed

• Hominins engaged in less fighting

Name the skeletal features that indicates a organism is bipedal.

• Long narrow pelvis, short legs, long arms

• No valgus angle, opposable big toe, arched foot

• Wide bowl shaped pelvis, valgus angle, arched foot

• S-shaped spine, long narrow pelvis, opposable big toe

Bipedalism most likely evolved because...

• Our ancestors relied on trees less and less

• The climate in Africa changed which lead to less rain forest and woodland to more open/savannah areas

• The climate in Africa changed which lead to less rain forest and more woodland areas

• The climate in Africa changed which meant our ancestors needed to communicate using language

What advantages did bipedalism result in (select all those that apply)

• Freed up hands

• Saves energy when walking long distances

• Faster travel

• Improved dorsiflexion

What is the correct order of species from earliest to modern humans?

• Paranthropus boisei, Australopithecus afarensis, Homo ergaster, Homo sapiens

• Homo habilis, Homo erectus, Paranthropus boisei, Homo ergaster

• Australopithecus afarensis, Homo erectus, Homo habilis, Homo heidelbergensis

• Australopithecus afarensis, Homo habilis, Homo erectus, Homo sapiens
